An audio conversion app (also known as an audio converter) transcodes one audio file format into another; for example, from FLAC into MP3. It may allow selection of encoding parameters for each of the output file to optimize its quality and size.
Freemake Audio Converter features a batch audio conversion mode to convert multiple audio files simultaneously. The program can also combine multiple audio files into a single file. [3] The software includes several ready-made presets for each supported output file format and the ability to create a custom preset with the adjustment of bitrate ...
Users can choose between various lossless direct audio/video transfers between container formats or lossy video/audio encoding, with encoding possessing the added ability to change video and audio specifications such as bitrate, frame rate, audio channels, resolution, sampling rate, and aspect ratio. SUPER is also able to utilize its back-end's ...
Audio file icons of various formats. An audio file format is a file format for storing digital audio data on a computer system. The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression.
ACT is a lossy ADPCM 8 kbit/s compressed audio format recorded by most Chinese MP3 and MP4 players with a recording function, and voice recorders.. Many models of recorder that use the ACT format do so only for their lowest-quality recording setting; if the quality setting is increased then a different format, typically WAV, is used, creating much larger files.
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). The codec can also be used by the .CAF file type container, though this is much less common.
MPEG-4 files with audio and video generally use the standard .mp4 extension. Audio-only MPEG-4 files generally have a .m4a extension. This is especially true of unprotected content. MPEG-4 files with audio streams encrypted by FairPlay digital rights management as were sold through the iTunes Store use the .m4p extension.
As such, the user normally doesn't have a raw AAC file, but instead has a .m4a audio file, which is a MPEG-4 Part 14 container containing AAC-encoded audio. The container also contains metadata such as title and other tags, and perhaps an index for fast seeking. [2] A notable exception is MP3 files, which are raw audio coding without a ...
