Breve descrizione:

Audacity è un editor e un registratore audio multitraccia facile da usare, compatibile con Windows, macOS, GNU/Linux e altri sistemi operativi. Sviluppato da un gruppo di volontari come software libero e open source.

Caratteristiche

Recording

Audacity can record live audio through a microphone or mixer, or digitize recordings from other media. With some sound cards, and on any recent version of Windows, Audacity can also capture streaming audio.

Export and import

Import sound files, edit them, and combine them with other files or new recordings. Export your recordings in many different file formats, including multiple files at once.

Sound quality

Audacity supports 16-bit, 24-bit and 32-bit (floating point) samples (the latter is Audacity’s default setting and preserves samples in excess of full scale).
Sample rates and formats are converted using high-quality resampling and dithering.
Tracks with different sample rates or formats are converted automatically in real time.

Plug-ins

Support for LADSPA, LV2, Nyquist, VST and Audio Unit effect plug-ins.
Effects written in the Nyquist programming language can be easily modified in a text editor – or you can even write your own plug-in.

Editing

Easy editing with Cut, Copy, Paste and Delete.
Find the spot to edit easily with scrubbing and seeking or Timeline Quick-Play.
Unlimited sequential Undo (and Redo) in the session to go back any number of steps.
Edit and mix large numbers of tracks.
Multiple clips are allowed per track.
Label tracks with selectable Sync-Lock Tracks feature for keeping tracks and labels synchronized.

Envelope Tool to fade the volume up or down smoothly.
