| Summary | 0000319: 32 bit export results in a wav full of zeros | ||||
| Description | I have an open bug (0000285) about session exporting crashing ardour and hanging jackd. To narrow down what could cause it, I tried exporting without any conversion: Stereo, WAV, 32 bit, Little-endian, 48khz (the sample rate I used), (conversion quality and dither type don't apply, as no conversion is done). I selected only the master bus out-1 and out-2 to be exported. Everything went fine, except AFTER the export is finished (status bar is full), I get this on the console: cannot use real-time scheduling (FIFO/9) (1: Operation not permitted) Then the export dialog closes, and after a few seconds I get a popup saying that jackd has thrown ardour out. The resulting wave is just full of zeros. If I export as a raw I can do this: $ cmp Session.raw /dev/zero cmp: EOF on Session.raw | ||||

please provide the ardour version info. i believe this is fixed in current CVS. |
|
|
Whoops. I knew I forgot something.. Ardour/GTK 0.453.1 running with libardour 0.728.1 |
|
|
I tried the nightly cvs snapshot, version: Ardour/GTK 0.454.0 running with libardour 0.729.0 I still get exported files full of zeros. |
|
|
libardour 0.729.0 is not the latest CVS. but thats not your fault. for some reason, the nightly build script has not run since march 7th, something i would not have noticed without this report. please pick up the new "hand-made" CVS tarball and test that one out. |

I got the new tarball and compiled, version is now: Ardour/GTK 0.456.0 running with libardour 0.731.0 I still get empty waves. Could this be a library version incompatibility? All libraries in use by ardour: ld-2.3.2.so libc-2.3.2.so libdl-2.3.2.so libgcc_s.so.1 libm-2.3.2.so libpthread-0.10.so librt-2.3.2.so libX11.so.6.2 libXext.so.6.4 libXi.so.6.0 libcrypto.so.0.9.7 libssl.so.0.9.7 libart_lgpl_2.so.2.3.16 libasound.so.2.0.0 libcurl.so.2.0.2 libgdk-1.2.so.0.9.1 libglib-1.2.so.0.0.10 libglib-2.0.so.0.200.3 libgmodule-1.2.so.0.0.10 libgtk-1.2.so.0.9.1 libjack.so.0.0.23 liblrdf.so.0.1.3 libraptor.so.1.1.0 libsamplerate.so.0.0.15 libsndfile.so.1.0.7 libstdc++.so.5.0.5 libxml2.so.2.6.6 libz.so.1.2.1 (btw. I produced this with: for FILE in $(ls -l $(ldd $(which ardour) | grep '=>' | sed 's/.*=> //' | sed 's/ .*//') | sed 's/.*-> //' | sed 's/.* //'); do basename $FILE; done This could be useful for mantis reports) |
|
|
can you do me a favor and try either (or both) 16 bit and float formats? |
|
|
16 bit and float work fine. |
|
|
tested 3 times at 24bits and 32 bits. considered fixed. |
|
|
Sorry for not testing this earlier. I just tried this, I recorded a few clicks and exported it to a 32 bit wave. The resulting wave was abs()ized. Except for the clipped samples which were at about -1. The session had one mono track and a stereo master bus. I exported through the master bus. I'll attach a sample of one exported click. |

32 bit exports are still distorted. I believe that for some reason, ardour isn't producing any negative samples. I've just exported a small session and tried opining it with audacity, sweep, snd, kwave and all point to the same direction. All samples are above or at 0. Ardour/GTK 0.548.1 running with libardour 0.851.1 |

Is this still an issue? |
