Let’s look at the steps in this algorithm more closely. 1. Divide the audio signal in frames. MP3 compression processes the original audio signal in frames of 1152 samples. Each frame is split into two granules of 576 samples each. Frames are encoded in a number of bytes consistent with the bit rate set for the compression at hand.

FLAC (Free Lossless Audio Codec) is one of the few audio formats that delivers truly lossless compression. FLAC is similar to a ZIP file, but is designed specifically for audio. FLAC is also open-source, and FLAC files can be played back on most MP3-compatible players.

Other audio compression algorithms address speech-only applications or provide only medium-fidelity audio compression performance. For example, Code Excited Linear Prediction (CELP)[3] is a speech coding algorithm, while µ-law and Adaptive Differential Pulse Code Modulation (ADPCM) are relatively simple compression algorithms that can provide medium fidelity audio …

Unlike the dynamic range compression used in recording studios, audio compression codecs don’t affect perceived loudness. Instead, audio coding compression uses clever algorithms to shrink down an uncompressed 50MB music file into something much more portable, say around 7MB, for example.

General purpose compression such as zip works on raw audio data, but better to use a method specialized for audio. Free Lossless Audio Codec (FLAC) is best for lossless compression. For lossy compression, which can make far smaller audio files than FLAC can, want to consider speech and music separately. mp3 is still the most well known and popular for music, but it is …

For common data compression, 7zip performs better than WinRar. However, for audio/video files, common data compression techniques like zip, winrar, 7zip have poor performance. You should use specific audio compression techniques like aac, amr, ogg, and specific video compression techniques like h.264, mpeg-4, etc.
15 Most Popular Data Compression Algorithms - Geeky Humans

Data Compression algorithms can be defined as the process of reduction in sizes of files at the time of retaining the same or similar to some extent of data. This is done by performing the elimination of unnecessary data or making the data again for higher efficiency.
