Recording Audio

[jameson]

Hello, how long can audio be recorded on Audacity and how to extend the time if possible??

In principle, the solution to recording over 13.5 hours is to use the latest 1.3 Beta version of Audacity. Here, samples are stored as 64-bit values (even on 32-bit machines), which at 44100 Hz sample rate offers a maximum recording length of a mere 58 billion hours.

58 billion hours is the theoretical limit, you'll run out of memory first ...

Examples of disk space usage when recording and editing at different quality settings:

44100 Hz, 32 bit, stereo = 20 MB of space per minute. 44 100 Hz and 32-bit are Audacity's default quality settings
44100 Hz, 16 bit, stereo = 10 MB per minute. CD quality
22050 Hz, 8 bit, mono = 1.25 MB per minute. This would be generally acceptable for speech recordings from lower quality sources
