Users can customize the output by altering the bit rate, maximum file size or bit rate and sample rate via "constant quality". [9] HandBrake supports adaptive deinterlacing, scaling, detelecine, and cropping, both automatic and manual. [2]
Sample-rate conversion prevents changes in speed and pitch that would otherwise occur when transferring recorded material between such systems. More specific types of resampling include: upsampling or upscaling; downsampling, downscaling, or decimation; and interpolation. The term multi-rate digital signal processing is sometimes used to refer ...
Audio Units allows sound file audio time stretching and pitch scaling (e.g., timestretch), sample rate conversion, and streaming over a local area network.It also comes with a set of AU plug-ins such as EQ filters, dynamic processors, delay, reverb, and a Soundbank Synthesizer Instrument.

ALAC supports up to 8 channels of audio at 16, 20, 24 and 32 bit depth with a maximum sample rate of 384 kHz. ALAC data is frequently stored within an MP4 container with the filename extension.m4a. This extension is also used by Apple for lossy AAC audio data in an MP4 container (same container, different audio encoding).
libsndfile is available for Unix-like systems, including Linux and Mac OS X, and for Microsoft Windows. [4] It is licensed under LGPL-2.1-or-later. [4] libsndfile is used, for example, by audio-editing software such as Audacity and Adobe Audition [3] and the MP3 encoder LAME. [5]

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 systems.
