Audio file bit rates are measured in thousands of bits per second, or kbps. I mentioned above that a CD contains audio at 1,411 kbps, and when you convert that audio to a lossy file, its bit rate ...

Lossless audio can also be used to preserve 100% of the information in a hi-res audio source like SACD or DVD-Audio (or music that is mastered in the studio at hi-res bit-depths and sample rates).

To get the bit rate, you take the sample rate and multiply it by the bit depth. You then take that product and multiply it by the number of channels of the audio (typically 2). Lastly, take that ...

The higher the bit depth, the more difference between the softest and the loudest sound possible. 16-bit audio has a total dynamic range of 96dB, jumping to 144db using 24-bit samples.

Bit rate can also be used to work out the size of an audio file if you know how long it is. For example, a 320kbps MP3 has 320,000 bits of data a second, which is 40KBps (note the capital B for ...

For mastering audio-only recorders, 24 bits is the norm, but even for portable digital audio recorders, 24-bit capability is becoming much more prevalent, with provisions for the user to choose a ...

Like all things digital, advances continue to occur in the world of codec development. These highly enabling technologies have attracted some of the best minds in the business, with many corporations ...

For audio purists, “real” Hi-Res Audio is typically considered to be digital audio that has a sample rate of 96kHz or higher and a bit depth of 24 bits or higher. Some high resolution audio formats ...

Upsampling is on the other hand a rate conversion from one rate to another arbitrary rate. Oversampling in the ADC has been around for quite a bit of time, while upsampling of audio that results in a ...

Dolby Digital and DTS can both deliver fantastic surround-sound experiences – but there are some key differences in the way that they achieve that end result. The major differences are the compression ...

When it comes to discussions of digital audio, you’ll quickly run into an alphabet soup of acronyms: MP3, AAC, ALAC, FLAC, WAV, DSD, and so on. It’s practically endless. You’d think that ...
