Clear explanations of how audio actually works — AI vocal separation, sample rates, the pitch/tempo/duration relationship, file formats, beatmatching, and the concepts behind the tools you use every day.
Lossy vs lossless audio, decided: what compression permanently throws away, what lossless keeps, the size trade-off, and a clear rule for which to use when.
A FLAC file is a lossless audio format that compresses sound with no quality loss — half the size of WAV, identical fidelity. Here's how it works.
An M4A file is an MPEG-4 container that usually holds AAC audio, sometimes lossless ALAC. Here is what it means and how to convert M4A to MP3.
A WAV file is an uncompressed, lossless audio format that stores raw PCM sound bit-for-bit — perfect quality, large size. Here's how it works.
