Pitch Tempo

Pitch Tempo is a free online tool for analyzing and altering audio tracks. It's designed for DJs, producers, and musicians who need to quickly find a song's key and tempo or make adjustments without installing any software. It all works in your browser.

You start by uploading an audio file up to 100 MB and five minutes long. The tool's AI automatically detects the original key and BPM. From there, you can use its conversational interface to direct the changes you want to make, such as transposing the key or adjusting the speed.

After making your edits, you can preview the result and download the new audio file. The main capabilities include:

• AI Analysis: Automatically finds the musical key and beats per minute.
• Pitch Shifting: Transpose the audio to a different key.
• Tempo Changing: Speed up or slow down the track without altering its pitch.
• Format Support: Works with MP3, WAV, AAC, and other common audio files.
• Direct Download: Preview your changes and download the edited file.

You can use the tool without an account, but your files and usage are limited. Signing up for a free account gives you higher usage limits and saves your tracks so you can return to them later.
