# Size limits for WAV and AIFF files

From Audacity Development Manual

'

WAV and AIFF files are limited to a maximum size of 4GB, see the following table for how this translates to time durations

## Approximate maximum time durations for WAV and AIFF PCM-encoded files

  Maximum sizes for files in time duration (hours:minutes)
  Sample Format | Stereo | Mono
  16-bit (default) | 6h:45m | 13h:31m
  24-bit | 4h:30m | 9h:01m
  32-bit | 3h:22m | 6h:45m

| These timings are the theoretical maximum times. You would be well-advised to restrict yourself to slightly lower limits to afford some head-room.
