Recording or exporting fails due to the 2 GB file size limit
- Live Versions: All
- Operating System: All
The file size limitation of a 32bit or 64bit application is 2GB.
The maximum duration of a single audio file can be calculated like this:
- 16 Bit = 2 Byte
- Stereo = 2 channels
- 192 kHz = 192000 samples per second
- 2 * 2 * 192000 Bytes/sec = 768000 Bytes/sec
- 60 sec * 768000 Bytes = 46080000 Bytes/min = ~44 MB/min
- 44 MB * 46 min = ~2GB
Maximum duration of a single file at different sample frequencies (stereo, 16-bit):
- 44,1 kHz: ~203 min (10 MB/min)
- 48 kHz: ~186 min (11 MB/min)
- 88,2 kHz: ~101 min (20 MB/min)
- 96 kHz: ~93 min (22 MB/min)
- 192 kHz: ~46 min (44 MB/min)
Calculate the file size of your audio recordings based on sample rate, bit depth, mono/stereo.
Issues arising due to the 2GB file size limit:
- A: When recording audio for a long time, Live suddenly stops recording and eventually crashes, even though there is enough free space left on the hard disk.
- B: When trying to export or consolidate audio with a large selected time range, Live shows the message: “Live only supports rendering files of less than 2047 MB”.
How to resolve this:
In general, using a lower sampling rate and bit depth (e.g. 44,1 kHz / 16-bit, CD audio quality) will result in a smaller file and may resolve the problem if higher settings had been used before.
If it is still required to do a recording that exceeds the 2 GB limit, you might consider using a different software which is able to automatically split recordings into multiple audio files. For example, Audacity can do this and is free.
If the problem occurs while rendering the whole Set, it should be exported in several smaller parts.
