What's new in this version:
- VU Meters added for both playback and recording. Click on the recording meter to monitor the input without recording.
- Export Multiple - new feature that lets you export multiple files at once, either by track, or split based on labels.
- Attempt to automatically correct latency in full-duplex recordings. (This does not work perfectly, and is not yet supported on all systems. It will improve in future versions.)
- Fixed a serious bug that could cause data loss when you save and then reload and re-edit an Audacity project containing repeated or duplicate data.
- MP3 tags dialog will only pop up the first time you export as MP3; after that it will not pop up again as long as you have filled in at least one tag.
- You can now add a label at the current playback position - in the Project menu, with a shortcut of Ctrl+M.
- Clicking on a label now selects all of the tracks, making it easier to use the label track to recall selections.
- Fixed a bug that caused problems with recordings over 45 minutes on some Windows systems.
- Mac OS X: Improved support for the Griffin iMic by fixing a bug that was causing it to always record in mono instead of stereo.
- Added support for Software Playthrough (listen to what you're recording while recording it, or while monitoring using a VU meter) - this makes it possible, for example, to record using one audio device while listening to it play through a separate device.
- Fixed a cosmetic bug that caused improper waveform display if you tried to open an Audacity project saved on a different platform (e.g., copying a project from a Mac to a PC).
- Fixed bug that could cause instability when pasting, splitting, or duplicating a label track.
- You can now change the font of a label track by choosing "Font..." from the label track's pop-up menu.
- Basic printing support has been added. Currently it scales the entire project to fit exactly on one page. Try printing in landscape orientation for best results.
- Mac OS X and Windows: Audacity ships with a newer version (1.0.1) of the Ogg Vorbis encoder. Vorbis compression will now have higher quality and smaller file sizes.
- Fix a bug that occasionally caused crashes when applying effects to split tracks.
- Zoom In / Zoom Out now properly disable when they're not available.
- Always delete temporary files created by previewing effects.
- Many other bug fixes and performance improvements.
