description: A technical look into time stretching in Audacity 3.4
---
For Audacity 3.4, we've added a new time stretching feature, which can be accessed by holding Alt (macOS: Option) and dragging the edge of a clip. Additionally, when you change the project tempo, all clips in the project are adjusted to the new tempo.
This feature uses a time stretching algorithm that originated in [Staffpad](https://staffpad.net) and marks the beginning of a wider code sharing effort. In the future, this code sharing will extend in particular to Musescore, which has various components we will use - such as buttons and the general UI system, but also larger features like the mixer - and also may turn bi-directional, with Musescore using some of our technology in the future. Audacity's continued efforts in librarization of the code base certainly make code sharing easier, both between Muse products and also with third party developers.

[insert release video here]
We are excited to announce Audacity 3.4, which adds the following features:
* **Beats and measures grid**: You can now easily align your audio clips to the musical tempo and rhythm of your project. The grid shows you the subdivisions of each measure depending on your zoom level, and you can snap your clips to the nearest beat.
* **Time stretching**: You can now change the duration of your audio clips without affecting their pitch non-destructively. Audacity 3.4 uses a state-of-the-art algorithm that preserves the transients and harmonics of the original sound, while minimizing artifacts and distortion. You can [learn more about it here](audacity-3.4-timestretch.md).
You can download Audacity on [audacityteam.org/download](/download).
