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.
LUFS vs RMS vs dBFS: three meters that measure different things. Learn which number to read for clipping, streaming targets, and real loudness.
Stem separation quality is measured objectively with SDR and subjectively by how much bleed and how many artifacts you can hear. Here is how to judge it.
A backing track is the pre-recorded accompaniment a musician sings or plays over. What it means, how it differs from a karaoke track, and how to make one.
True peak (dBTP) is the real level between digital samples, so a '0 dBFS' master can still clip after MP3 encoding. Here is why engineers leave headroom.
An acapella is a song's isolated vocal with the instrumental stripped away. What the term means in music production and how an acapella extractor makes one.
An instrumental track is a song with the lead vocal removed. What the term means, how it differs from a karaoke or backing track, and how to make one.
