## About

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.

## How to use

1. **Add it in ChatGPT** Open SignalGrade in ChatGPT's Plugin directory (button above), select + to add it and sign in if asked.

2. **Use it in a chat** Type @ in the composer and pick SignalGrade, or start your message with its name. ChatGPT may also suggest it when it fits what you ask.

## Example prompts

- "How does my mix compare to this reference?"
- "Will Spotify turn this master down?"
- "Is anything wrong with this master before I release it?"
