Download Audacity 1.3.7 Beta

On Wednesday, after a long time, a new version was released in the development branch of the open source audio editor Audacity. Available for Windows, Linux and Mac OS X, the program can record sound, import and export wav, aiff, ogg and mp3 files and has unlimited undo function. In addition, Audacity has a lot of effects on board, such as fade-in and fade-out, echo, tempo change and noise reduction. More effects can be added easily as the program supports both vst and ladspaplugins. The changelog of this release shows the following changes:

Cross Platform Bug Fixes:

• Muting/soloing caused incorrect channel results in exported stereo files
• Noise Removal and all Nyquist effects pasted the original unmodified audio at the end of the modified region
• Noise Removal inserted a tail of low level noise at the end of the modified region
• Nyquist and Compressor plug-ins did not display moving bars in progress dialogue and over-estimated “Remaining Time”
• Canceling Nyquist effects deleted unprocessed audio
• Change Speed ​​and Change Tempo failed to modify the original selection length
• Cut lines invisible
• Fixed various bugs importing multi-stream files via FFmpeg
• File > Export as WAV could be corrupted if overwriting an imported WAV read directly from the file
• Export multiple “Other uncompressed files” choice always produced 16-bit PCM audio irrespective of chosen options.

• MP3 ID3 Genre tag misread on import if the genre list in Metadata Editor was opened and saved
• Exported metadata tags in MP3, OGG and FLAC often not seen by player software – now substantially improved

Other changes:

• Latency correction should be improved for many users by employing a fixed rather than variable correction
• Grouping of Effects into categories turned off until a way is added for users to do so themselves
• Numerous minor interface improvements such as Metadata Editor navigation, new “hh:mm:ss + hundredths” selection format
• Note: Windows users wanting to export MP3 files will require the latest version of the LAME encoder from here.
