Free browser calm-sound studio with soft noise and ambient beds. Four free presets in the browser; optional paid unlock for the full studio. Inclusive, no signup to try.
Pitch & Speed changes the key and the tempo of any song separately: slow down a fast solo without changing its pitch, transpose a song to suit your voice or instrument, and loop the bar you are learning with A-B markers. It detects key and BPM, has a 10-band equaliser and reduce vocals, and exports M4A or WAV. For musicians who practise with recordings.
