2. Audio bit depth - Wikipedia

   en.wikipedia.org/wiki/Audio_bit_depth

   Audio bit depth. An analog signal (in red) encoded to 4-bit PCM digital samples (in blue); the bit depth is four, so each sample's amplitude is one of 16 possible values. In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample.

4. Single-precision floating-point format - Wikipedia

   en.wikipedia.org/wiki/Single-precision_floating...

   Single-precision floating-point format (sometimes called FP32 or float32) is a computer number format, usually occupying 32 bits in computer memory; it represents a wide dynamic range of numeric values by using a floating radix point. A floating-point variable can represent a wider range of numbers than a fixed-point variable of the same bit ...

5. WavPack - Wikipedia

   en.wikipedia.org/wiki/WavPack

   WavPack compression can compress (and losslessly restore) 8, 16, 24, and 32-bit fixed-point, and 32-bit floating-point PCM audio files in the .WAV file format. It can also handle DSD input in DSDIFF or DSF format. [2] It also supports surround sound streams and high sampling rates. Like other lossless compression schemes, the data reduction ...

6. Fixed-point arithmetic - Wikipedia

   en.wikipedia.org/wiki/Fixed-point_arithmetic

   Specifically, comparing 32-bit fixed-point to floating-point audio, a recording requiring less than 40 dB of headroom has a higher signal-to-noise ratio using 32-bit fixed. Programs using fixed-point computations are usually more portable than those using floating-point, since they do not depend on the availability of an FPU.

7. IEEE 754-1985 - Wikipedia

   en.wikipedia.org/wiki/IEEE_754-1985

   IEEE 754-1985. IEEE 754-1985[1] is a historic industry standard for representing floating-point numbers in computers, officially adopted in 1985 and superseded in 2008 by IEEE 754-2008, and then again in 2019 by minor revision IEEE 754-2019. [2] During its 23 years, it was the most widely used format for floating-point computation.

8. Audio converter - Wikipedia

   en.wikipedia.org/wiki/Audio_converter

   An audio converter is a software or hardware tool that converts audio files from one format to another. This process is often necessary when users encounter compatibility issues with different devices, applications, or platforms that support specific audio file formats. Audio converters can be employed for a variety of purposes, ranging from ...

9. Audio Interchange File Format - Wikipedia

   en.wikipedia.org/wiki/Audio_Interchange_File_Format

   Audio Interchange File Format (AIFF) is an audio file format standard used for storing sound data for personal computers and other electronic audio devices. The format was developed by Apple Inc. in 1988 based on Electronic Arts ' Interchange File Format (IFF, widely used on Amiga systems) and is most commonly used on Apple Macintosh computer ...
