| Summary | 0007625: Recording for a long time creates wav files longer than the maximum allowable length of a wav file | ||||
| Description | Recording in Ardour (I was using version 4.60 bundled with Ubuntu Studio 16.04) for sufficiently long that the wav files in interchange/projectname/audiofiles become larger than 4Gb causes problems when reloading the project, as Ardour treats the file size as whatever it is MOD 4Gb. The unsigned 32 bit integer for the file length inside the wav header would seem to be the limiting factor. No problems are apparent during the recording process, but when the project is reloaded, the available length of audio is just the first FILELENGTH MOD 4Gb. | ||||
| Steps To Reproduce | Record a track for sufficient length of time so that the WAV file created is greater than 4Gb in length. In my case, I was recording a 6 hour live event for a radio programme with several tracks at 16 bit, 44.1KHz. File size of the resulting WAV files in the interchange/projectname/audiofiles folder was 4.3Gb. When the project was reloaded later, only the first 0.3Gb of audio was available. | ||||
| Additional Information | I was able to recover my data by splitting the WAV files into smaller chunks and adding WAV headers, then importing back into Ardour. I suggest that either Ardour starts making another WAV file when the maximum size is reached, or that the WAV 64 format is used for for the interchange files. | ||||

Ardour from ardour.org comes with libsndfile that automatically upgrades .wav files to .w64 when the limit is reached. I don't know what libsndfile/ardour versions Ubuntu ships and how Ubuntu configures those, so preferably you'll file a bug with Ubuntu for this issue. It is not under our control. Meanwhile you can use Ardour-menu > Session > Properties > Media and select "Wave 64" manually. To recover the files, sndfile-salvage (from the sndfile-programs package or https://github.com/erikd/libsndfile/blob/master/programs/sndfile-salvage.c ) may come in handy. |

Thanks for the very helpful information x42. I will investigate further and file a bug with Ubuntu if appropriate. |

Check ardour-menu > Help > About > Config The compiler-flags at the end include a '-DHAVE_RF64_RIFF' if Ardour was compiled and linked with a recent libsndfile that supports this feature. (libsndfile 1.0.26 or newer) |

That's the problem then. -DHAVE_RF64_RIFF is not present in the Config.

Where did you get Ardour from? |
|
|
It was the version bundled with Ubuntu Studio 16.04 |
|
|
Yes, almost all Linux distributions fail to build Ardour correctly. This is why we only encourage and support the use of the version we distribute, via http://ardour.org/download |
