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.

Comparing audio compression using wavelets with other audio compression schemes Abstract: Speech compression is the technology of converting human speech into an efficient encoded representation that can be decoded to produce a close approximation of the original signal. In this paper, we propose a new algorithm which compresses speech signals ...

Peak mode reacts faster to short peaks within an audio signal. This mode is more aggressive and responsive to transients. It works great for taming transient spikes and limiting tasks. RMS Mode RMS mode is less sensitive to short peaks. This mode applies compression only when the incoming level exceeds the threshold for a slightly longer time.

Two popular lossless audio codecs – FLAC and Apple Lossless (ALAC) – both use schemes based on ZIP compression. Focusing on data compression only means preserving many of the details that MP3 and other lossy standards would obliterate. If you have sharp ears and a high-quality listening setup, the difference can be palpable.

Compression Every compression scheme has three stages: The input data is transformed to a new representation that is easier or more efficient to compress. We may introduce loss of information. (Quantization is the main lossy step ). Coding. Assign a codeword (thus forming a binary bit stream) to each output level or symbol
