Description
Give ChatGPT tools to help you analyze and improve your music. Upload a track and ask for feedback, compare it to a reference, or check it before release. SignalGrade measures: - Loudness, true peak, and how Spotify, Apple Music, YouTube, Tidal, and Amazon Music will adjust your volume - Dynamics and tonal balance across 9 frequency bands - Stereo width, phase, and mono compatibility - Problems like clipping and DC offset WAV or FLAC works best, but MP3 works too. Files are deleted as soon as they're analyzed.
