8 Things You Should To Do For Record Good Audio

Monitoring speakers are necessary when recording audio, especially if you want to achieve great results. However, studio speakers can’t do the job by themselves, so if you already have a pair of high quality studio monitoring speakers yet are still making crappy audio, then maybe you’re doing a few things wrong. Here are 8 things you can do to achieve the results you want:

Record with good-sounding instruments
Before you start recording, you need to make sure that none of the instruments are faulty or out of tune. If an instrument needs new strings or heads, replace and tune it before the session. Old guitar strings also sound bad, so you might want to restring your guitars as well.

Avoid recording your guitar with reverb
You should only record your guitar with reverb if it’s absolutely necessary and if you’re 100% sure that you’re not going to change it during mixdown. Otherwise, you should record it dry, especially if you don’t really think it’ll fit with the arrangement. If the guitarist can’t play without reverb, you can make up for it by adding some to his headphones from your software.

Avoid recording in the red
Digital clipping makes a recording sound bad, and once you do that you can no longer go back and fix it. This is why you should avoid recording in the red as much as possible. You can just record at a lower volume, and just raise the volume in your mix. Again, you can’t remove clipping, so you might as well just prevent it from happening.

Use the right microphone(s)
Not using the right microphone can result in an awful vocal track, so make sure you are actually using the right one. Condenser microphones are what you’d normally see in studios, and probably what you should be using. Dynamic microphones work for some vocals and styles, but obviously not everything. Compare the two and use the one that fits your recording needs.

Record with good-quality cables
If you want a high-quality recording, it’s ideal to invest in high-quality equipment. Cables do matter even though they may not matter as much as the microphone you’re using or the kind of pre-amp you have. They still have a say in the overall sound of the record, so don’t go cheap.

Take your time
Rushing is often a bad thing, and this also applies to recording audio. While some artists may work under pressure, the majority generally don’t. Don’t expect a vocalist to be able to produce all the vocal tracks to an album in just a short time. Perfection takes time.

Be in the correct position
A good-sounding room and some acoustic treatment are definitely necessary for recording a great audio, but so does the position of the microphone. You can’t just stand in the middle of your bedroom and sing into the microphone you’re holding and still expect to record a good audio. Not all positions are ideal for achieving a great vocal performance, so determine where you should properly position yourself in the room before you start recording. The position of your monitoring speakers also matter, as they will sound different depending on where they are in the room.

Record at 24 bits instead of 16
Now that we have 24 bits, it doesn’t really make sense to record at 16 bits anymore, unless your computer is really slow. It gives you more range of possible volumes in your files and you won’t have to worry about recording into the red. Plus, if you really need it to be 16 bits, you can always convert it to 16 from 24.

If you are already doing all of these things yet the audio tracks you record still sound bad, then the problem is probably your monitoring speakers. Not all studio speakers can do the job right. And if your monitoring speakers are indeed the problem, then it’s most likely time to invest in new ones. You can check out if you need some advice on which ones to get.

Studio monitoring speakers come in different brands, sizes, materials, and shapes, so it may take you a while to find the best ones. However, if you take the time to read, you’ll definitely find what you’re looking for.

Here Digital Signatures and Certificates

When we think of VPNs, often our first thought is that of encryption of the user data. But adversaries or those intent on reading the data could However an attacker could record a conversation and then replay the replies between to participants. What we need to do is to be able to ensure the source of the data is genuine, and that is where digital signatures and certificates comes in.

To construct a Digital Signature, public key encryption systems must be in place. The construction of the Digital Signature entails applying a hash function to the message by concatenation of the message with a known secret key and then applying a mathematical function which will produce a fixed length output known as the digest. The digest is then encrypted with the public decryption key which produces a signature that can be appended to the message to verify that the message is from the genuine source.

The receiver recalculates the hash function and compared with the signature after applying the public key. If the two match, then because only the originator could have known the hash function and the private key, the message must be genuine.

Message Digest algorithms use Hash functions to map many potential inputs to each of a large number of outputs. What is normally produced is a fixed length field, typically a few hundred bits in length. A secret key is shared between sender and receiver and by concatenating this with a message for transfer, the digest is produced.

MD5 (Message Digest 5) is probably the most common hash function used, and it produces a 128 bit digest which is often appended to the header before the packet is transmitted. Any change in the message will cause the digest to change, and even the source and destination IP addresses can be used together with the message contents when creating the digest, which validates the addresses.

Another popular hashing algorithm is SHA (Secure Hash Algorithm) that produces a 160 bit digest ensuring greater security than MD5.

It doesn’t matter how long the digest is, an identical digest will always result for an identical packet. But anyone wishing to attack the system could monitor exchanges and determine which packets sent in what ever order would result in some known result. This result could therefore be reproduced by replay of the messages. This is known as a collision attack.

HMAC (Hash-based Message Authentication Code) can be used to combat collision attacks by including two calculated values know as ipid and opid, which are initially calculated using the secret key for the first packet and recalculated for subsequent packets. The values are stored after each packet and recovered for use in the calculation of the digest for the next packet. This ensures that the digest is always different even for identical packets.

A Digital Certificate is produced using some known information such as name, address, mother’s maiden name, house number, National Insurance number, or indeed anything. This information is appended to the public key and then used as part of the hash function to create the digest which is then encrypted using the private key through a secure encryption system such as RSA or AES.

A Digital Certificate can be validated by passing it through the public encryption process with the public key for the user to yield the digest. This can be compared with the calculation of the digest from the claimed identity of the user and their public key. If the two calculations yield the same result then the certificate is valid. Digital certificates are appended to messages to verify the authenticity of the source of the message.


About Scanning Solutions Improve Your Workflow

Many companies operate under the impression that scanning documents is a simple, but limited, method for document storage. Although scanning does indeed reduce storage costs, there are many more benefits to implementing a scanning solution than storage alone. In fact, electronically archiving your business records is just one small step you can take toward improving operational efficiency and lowering document costs.

Regardless of your specific industry, a successful scanning solution will reap many benefits, all of which will ultimately have an impact on your bottom line. Once your documents are scanned, document management software ups the ante by adding a laundry list of practical benefits that can save your business time and money. Scanning paper documents and storing them electronically also creates a centralized file cabinet with secured areas, limiting access to only those employees with permission to access specific files. In addition, the document management software records who accessed the document and provides an audit trail. Consider the fact that 90% of US companies had a security breach in the last year from people accessing hardcopy documents. Sadly, many of these breaches go undetected because there is no way to know who accessed these documents when they are in paper form.

Imagine the amount of time you spend hunting down specific documents. Now multiply that amount of time by your total number of employees. If time is money, a successful scanning solution will turn back the clock.

Here are just a few of the many benefits of a scanning solution:

• Increased productivity

• Shortened document retrieval time

• Increased compliance

• Reduced labor costs

• Streamlined auditing

• Reduced storage costs

It’s easy to imagine just how valuable combining a scanning system with a document management solution can be. And it’s also simple to see how inefficient it is to manage your business documents without these tools. For example, without a proper system in place, a customer might call with a question regarding his or her order. Because of the many steps involved in a given purchase, your employee must follow a veritable trail of breadcrumbs in order to answer the customer’s inquiry.

Oftentimes, this results in time lost, which, for your average customer, is frustration gained. A successful scanning and document management solution will allow all the documents associated with particular orders to be accessed by anyone at any time. This way, when the customer calls, your employee is ready with the correct answer almost immediately.

So, while scanning business documents is often useful, it is barely scratching the surface of scanning potential. Embrace the process of real-time scanning, and watch as your company’s workflow drastically improves.

Now Put Your Best Foot Forward With Morph Transitions with PowerPoint 2016

Building a swashbuckling PowerPoint presentation indeed is not an easy affair. To craft a good example of PPT one requires regimentation of thoughts, precise content and off course good transition features too.

Working on the last aspect mentioned above, Microsoft has brought a brand new transition type or feature simply known as “Morph”. With this innovative “Morph” feature it is now lot more simple to craft attractive slide templates as the building block for an exceptional PPT example. Most amazing facet of Morph is that it can be applied automatically to move or transform objects, shapes, charts, SmartArt, pictures, words or characters across the PowerPoint templates and best part is that all this can be done with just one click.

Going by the dictionary meaning Morph is defined as “To change smoothly from one image to another using computer animation”. This is what this new automatic feature encompasses for users i.e. smoothly bring change.

With Morph’s cool features it is pretty simple to zoom in, spin, resize and alter colors of an object in a slide PPT. Similarly, word rotation, font resizing, alteration in font type etc. can also be applied. There is more, as movement of characters can also be achieved with Morph. One significant point that needs to be underlined here is, keeping the character case or capitalization same for the whole slide is essential to apply this transition. Last but not least, PowerPoint 2016 and Office 365 is an essential requirement to apply Morph.

Now, let’s comprehend how exactly Microsoft’s new automatic Morph feature works.
First and foremost, to apply any sort of Morph two identical PPT slides are required. This can be obtained by copying one slide design. If not identical, than the two presentation slides should have at least one common feature so as to apply any sort of Morph.

Coming to application of Morph in PowerPoint Presentations, than it is a short and simple just a three step procedure:

1. Firstly, make a replica of the original slide by clicking “Duplicate Slide” option or simply with Ctrl+D.

2. Secondly, apply desired alterations in the replica or second PPT slide.

3. Finally, apply Morph transitions in replica or second PPT slide to move objects, words or character as per your style.

Let’s have a close look at the step by step procedure for better comprehension of the Morph application.

1. To apply the transition just select or pick the second replica slide.

2. After this bring the cursor on the ribbon or tool bar to select “Transition Tab” or in case of Android “Transition Effect”.

3. A menu will open here. From this menu select “Morph”.

4. On selecting “Morph”, further various “Effect Options” will open like Objects, Words or Characters.

5. Now select the desired option as per requirement to apply Morph.

6. Apart from this, adjacent to “Effect Options” other options like of “Sound”, “Duration” and “Apply to all” will highlight.

7. Set these parameters as per the requirement of the specific PowerPoint show.
In nut shell, Morph actually bring myriad of effects to make a PPT model truly a jaw dropping one. Another equally significant factor here is that it saves users precious time, which otherwise could have gone waste to create same effect with Motion Path Animation.

By and large, Morph makes object, word or character movement pretty smooth thereby giving a professional touch. Moreover, as Morph is an automatic transition feature hence there is no need to understand the theory. Simply click and start!

The Lithium-Ion Battery Pack

Batteries today are omnipresent today that they are invisible to us. Running in cars, digital cameras, drones, bulbs, mechanical tools, inverters, ships, trains, airplanes, windmills and even in satellites. The basic science behind the battery is chemical energy converting to electrical energy containing three main components: Anode, Cathode, and Electrolyte. The revolution in the battery over the years are through several stages of chemical combinations and implementations. Starting from Voltaic Pile to Daniell Cell, then from Lead-Acid to Nickel Cadmium battery, further evolving to Alkaline Battery, Nickel-Metal Hydride (NiMH) and then finally to Lithium-ion battery. These are available in all shapes and sizes as per the need along with its possibly packed power capacity.

Working: The Lithium-ion battery pack consist of graphite, oxygen, metal, and of course lithium, which runs in a cycle of discharging and charging. While producing energy, the lithium moves back to the positive cathode across the electrolyte, and while charging, the ions move to the positive anode. This cycle repeats over the course of time and degrades the potency of the ions in providing the electric charge. The lithium-ion has 250Wh/kg (Watt-hours per kilogram) of energy while NiMH has mere 90Wh/kg. This is a vast difference for a small, portable and noiseless rechargeable battery.

Concern Parameters: The 10 parameters that a Lithium-ion battery pack’s development covers are high specific energy, specific power, affordable cost, longer life, better safety, wide temperature operating range, non-toxic, fast charging, lower self-discharge and longer shelf life. In the early stages, the cost of a Li-ion battery was $3000 per kWh, while Lead-acid battery cost $150 per kWh. But over the years, due to multiple benefits of Li-ion battery pack, being 150Wh/kg more than the NiMH, the cost is dramatically falling costing now $150 to $240 per kWh. Tesla’s goal is to reach $100 per kWh on lithium-ion battery packs for the cars.

NEW ERA: In 2005, there was a total of around $4900mil in the sales of lithium-ion batteries while in 2015 it is spiked to $15200mil wherein $4800mil is in automotive alone. It is expected to reach 10% on the total number of cars on the road to be battery EVs by 2020 from 0.3% today and to 35% by 2035. There is an even higher growth rate in China, Europe, and Japan when compared to the US. Statistically consuming 1900TWh for Li-ion battery pack by 2035, which is equivalent to power the whole of US for 160days.

FUTURE: There is still a lot to develop the battery technology as over the years we haven’t come up with anything further than lithium-ion battery packs configured in parallel or series to deliver the desired voltage, power density, and capacity. We sure have changed the contents and the proportion of the combination of raw materials to enhance the capabilities, but there is still a lot of work that has to be put into the battery technology. The targets are to reach over 700Wh/kg to that of 400Wh/kg we are on today. By 2020, 75% of batteries are expected to contain cobalt, in some capacity at least along with better anodes and enhancing electrolytes.

In the long run, lithium ion battery pack is to be cheaper and more efficient over to the existing ones. Moreover, Lithium Air technology is in cultivation, which shall have 10times the energy density than Li-ion. The world for lithium ion battery pack isn’t going to end for the next half century at least, making it the highest developing area in technology.


This Definition of VPN Authentication and Encryption

The fundamentals of creating a VPN are Authentication, strong Encryption and a method of secure Key Exchange. Authenticate the users, securely exchange keys for encryption then encrypt the data using the generated keys.

Authentication is used to validate a users identity using one or more of a number of methods:

Something you have – can be a key card, a security pass, drivers licence, a passport or similar. The possession of one of the above items is usually enough to confirm the identity of the holder. The problem with this is that the device can be lost or stolen, and sometimes used by other persons.

Something you know – a password, pass phrase or some other known information that can be used to calculate function from a secret message.

Something you are – A physical characteristic of your body such as your finger print, the retina print of your eye or your DNA.

Encryption is a means of taking some plain readable text into a cipher text utilizing some form of algorithmic mapping. The intended receiver of such a cipher text must have the means to reverse the process by knowing the same algorithm, but an attacker cannot know the process.

Encryption systems must use mathematically complex algorithms so as to provide a good enough deterrent from attackers to be able to use some brute force method of calculating the algorithm in use. Two common methods of encryption are Symmetric Encryption Systems and Public Key Encryption Systems:

Symmetric encryption simply uses an identical key for encryption of the plain text and decryption of the cipher text. and decryption at both ends. The encryptor applies the key to the plain text data which results in a cipher text. The decryptor reverses the by applying the same key to the cipher text to reveal the plain text data. The most common symmetric encryption system is the Data Encryption Standard (DES), of which there are several variations.

Public Key Encryption systems are a lot more complex than symmetric encryption systems such as DES and depend upon mathematical functions that are often referred to as “trap-door” functions. They involve complex mathematical formulae which normally involve exponentiation to high powers, modular arithmetic and the products of large prime numbers. The algorithms yield an encryption mechanism and an encryption key which can be made public and a decryption algorithm and decryption key that is kept secret. The mathematics of the algorithms is so complex that it is not possible to deduce the decryption mechanism from the encryption mechanism alone.
