Demystifying Audio Formats: What Format Is It Advisable To Record In?



There are numerous audio formats available, the ones should you want to record your audio in? An audio format is really a file format where music is stored on your computer. You can find an array of formats, like wav, mp3, aiff, wma etc. To learn the visible difference between various formats, we must first understand terms compressed and uncompressed formats.

Uncompressed Zvuk Formats

Uncompressed audio formats are bulky files and consume considerable space on the hard drive or storage drive. The main advantage of uncompressed audio formats is the excellence of the digital audio remains intact, since it is unchanged. It gives you the identical quality; regardless of how many times you process or re encode it.

Compressed Audio Format

Compressed audio formats compress digital audio data, leading to smaller files. You may release valuable space on your hard drive by making use of compressed audio formats.

Compressed audio formats are further categorized into 2 two groups:

Lossless Compressed Audio Formats

These audio formats compress digital audio data, however, there is no lack of data or degradation of audio quality throughout the compression process. The optimum instance of such format is flac.

Lossy Compressed Audio Formats

These audio formats compress digital audio data, but are recognized to eliminate certain information and frequencies to minimize the file size. lossy compressed audio formats causes degradation in audio quality. The visible difference in audio quality could be small or large, based on just how much data has become removed. Also, each subsequent processing or re encoding can result in more quality loss. The classic illustration of lossy compression is MP3.

Which recording Format is the best for me?

To find the best recording format, we have to understand 2 more terms, Sampling and bit rate. Digital audio has two primary qualities that compose just how the audio is described. - sampling rate and bit rate.

Sampling Rate

If you are recording audio digitally, this device (say, your pc) receives the audio signal, by breaking it into "snapshots" or samples. In recording technology, the volume of samples received per second is called the sampling rate. The idea resembles an electronic movie camera that records a variety of image frames per second and plays it back to be a continuous moving image. Similarly, you enjoy uninterrupted audio playback. Sampling rates are measured in hertz and represents the sound frequency range. Higher the sampling rate greater is definitely the audio quality and ensures greater precision within your high notes and low notes. Standard CD quality incorporates a sampling rate of 44, 100Hz or 44.1 KHz. Sampling rates start from 8000hz(suprisingly low quality) to 196,000(very good quality, with extreme huge files).

Bit Rate

In digital multimedia, bit rate often means range of bits used per unit of playback time for you to represent a continuous medium for instance audio. Let us understand what the bit rate actually represents. While sampling rates are variety of samples recorded per second, bit rate signifies the characteristics of every individual sample recorded. Returning to the digital camera example, bit rate is the same as pixels in digital images. Higher the pixels, better is definitely the image quality. Similarly, higher the bit rate (also referred to as bit depth), better will be the audio quality. By way of example an 8 bit audio will sound grainy and harsh, while a 16 bit audio sounds a lot better. Standard CD format has 44.1k sampling rate put together with 16 bit rate.
