Acoustica is an audio editing program from Acon Digital Media. Acon version 3.3 has been released, adding quality enhancement of old LP or tape recordings, effects chaining and many other tweaks. Acon say that Acoustica’s audio editing engine allows unlimited undo and redo levels, fast non-destructive editing and 24 or 32 bit editing with up to 192 kHz sampling rate. You can import tracks from audio CDs and create audio CDs with your edited material without leaving the program. Acoustica reads and writes Ogg-Vorbis, Wave Audio, Windows Media Audio, MP3 and Sun Audio files, and imports audio tracks from MPEG Video AVI and WMV files. It seems to have decent features for such an inexpensive program.

More details from the website: The new Cleaning Wizard simplifies the transfer of LP records or audio tapes to CDs. The Cleaning Wizard automates the whole process from recording and track splitting to audio restoration and CD recording.

The new effect chain editor in version 3.3 allows the user to chain internal processing tools and plug-ins. The chains can be saved including their settings for later use. Each processing step in the chain can be bypassed and the processing order changed by drag and drop. Full feature highlights are as follows.
