Category: Audio Group: 0.7.x Status: Open Resolution: None Priority: 5 Submitted By: Hartmut Noack (zettberlin) Assigned to: Robert Jonsson (spamatica) Summary: Incorrect graphs on Wavetracks Initial Comment: When i import a wavefile to a track i do not get a usable graph - i can see Audioevents in the track but as the cursor passes the region, there is nothing played and as the cursor passes empty regions in the graph, it plays the imported. If i change the file by using an external editor, the changes are reflected in the graph but not played as expected.(BTW: i had sweep set as the default waveeditor - strange as it does not work with jack... - i changed this to mhwaveedit - this one cooperates very good - so IF the wavetracks would be played as expected, Muse could even challenge Ardour regarding editing-comfort for Audiotracks ;-) ) ---------------------------------------------------------------------- >Comment By: Robert Jonsson (spamatica) Date: 2006-09-19 21:24 Message: Logged In: YES user_id=81832 ping times.... oh the joy... I have been unable to recreate this persistently. There _is_ an issue relating to the wav-cache. Changing the external file or importing a new file may not become active until the old file has been flushed from the cache (takes perhaps 5 seconds). ---------------------------------------------------------------------- Comment By: Hartmut Noack (zettberlin) Date: 2006-03-22 00:04 Message: Logged In: YES user_id=843133 --- An idea. is it possible that the file you imported had a name that had been used previously in MusE? No - the file is all new - i use wavefiles seldom with muse... Now i got something new to report: as i reopened the project with the wavefile in question today, the unwanted effect is gone - everything plays as expectetd - even dragging the file in the timeline works OK. But if i import another file to the same session - it is the same trouble again (BTW: "internal filebrowser" means the builtin QT-Browser, that is called by Muse, if i use file|import wave) So the seams to be something evil sneaked into the importfunction.... If i drag a file from Konqueror it is the same and i get this in the console: WaveTrack::getData(Track 4) fifo underrun FIFO 0x896df70 underrun... WaveTrack::getData(Track 5) fifo underrun FIFO 0x899ee30 underrun... WaveTrack::getData(Track 4) fifo underrun FIFO 0x896df70 underrun... WaveTrack::getData(Track 5) fifo underrun FIFO 0x899ee30 underrun... WaveTrack::getData(Track 4) fifo underrun FIFO 0x896df70 underrun... WaveTrack::getData(Track 5) fifo underrun FIFO 0x899ee30 underrun... WaveTrack::getData(Track 4) fifo underrun could there be a workaround by tuning th audiobuffersize for Jack ? If i close muse and jack and then reopen, the result is as expected: graphs and sound are in perfect sync... ---------------------------------------------------------------------- Comment By: Robert Jonsson (spamatica) Date: 2006-03-21 22:45 Message: Logged In: YES user_id=81832 "Audiofilemanager" now you have me confused, I don't think we have one :-D --- An idea. is it possible that the file you imported had a name that had been used previously in MusE? The wave-graph is cached in the files ending with .wca. If the files are manipulated outside muse it is possible to end up with a wave file and wca file which do not belong together. You can test this by removing the wca file, it should be regenerated the next time the file is used. ---------------------------------------------------------------------- Comment By: Hartmut Noack (zettberlin) Date: 2006-03-20 02:12 Message: Logged In: YES user_id=843133 >Do you have any "nonstandard" settings? I dont think so, yet i run the whole thing with a default-kernel an use the hw-monitoring of the envy24 to get the Sound in time... Ardour and mhwaveedit show and play Wavefiles exactly as expected... >menu alternative or drag&drop? I import via menu. First into the the internal Audiofilemanager and from its Window i drag the segments to their tracks... ---------------------------------------------------------------------- Comment By: Robert Jonsson (spamatica) Date: 2006-03-19 21:42 Message: Logged In: YES user_id=81832 I'm puzzled. Do you have any "nonstandard" settings? Jack samplerate? Did you import with the menu alternative or drag&drop? ---------------------------------------------------------------------- Comment By: Hartmut Noack (zettberlin) Date: 2006-03-19 14:03 Message: Logged In: YES user_id=843133 Dohh - i forgot to mention my systemsetups: 1.)
