# Audio to MIDI

> Turns an audio recording into MIDI notes with Gridshift's own pitch-detection model, which runs on your Mac. Select an audio clip, press ⌘K and run Convert Audio to MIDI….

## Convert audio to MIDI

Select an audio clip, press `⌘K` and run **Convert Audio to MIDI…**. A new instrument track appears with the extracted MIDI clip.

## Convert only one phrase

Trim the clip to the phrase you want, then run **Convert Audio to MIDI…** on it. Only what the clip plays is analyzed.

## Good to know

* **The original audio clip stays unchanged.**
* **It is polyphonic.** Chords, melodies and several instruments at once. Sustained and plucked single-instrument parts work best: piano, electric piano, synth lead, bass, voice.
* **Starts are far more accurate than ends.** Expect to correct the note lengths in the [piano roll](https://docs.gridshift.studio/edit/piano-roll.md).
* **Strummed chords are a known limit.** Notes that start within a few milliseconds of each other can be merged or misplaced, and the first note of a strum is the least reliable.
* **Under Punchy, notes land where the hits are in the original audio**, before warping. Smooth and Pitch warps are followed ([Time Stretching](https://docs.gridshift.studio/timing/time-stretching.md)).

> **What else should I know?**
>
> * **Velocity is predicted, not measured from the peak.** It tracks how hard each note was played, not the level of the recording.
> * **The model is Gridshift's own and runs on your Mac**; no audio is uploaded.
> * **Convert Audio to MIDI… is in the Command Palette's Audio Tools group.** With no clip selected it reads **No Audio Clip Selected**, with a MIDI clip **Audio Clip Required**.
