[Bug 20484] New: Audio distortion using Jack
http://bugs.winehq.org/show_bug.cgi?id=20484 Summary: Audio distortion using Jack Product: Wine Version: 1.0.0 Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P3 Component: gdi32 AssignedTo: wine-bugs(a)winehq.org ReportedBy: p.drezet(a)inx-systems.com When using Jack as the audio back end for wine low level but significant distortion is heard and measurable on the output. The level of distortion is sufficient to make wine jack unuseable for medium quality audio applications (i.e. quality is rediced to equivelant of 32kbs - mp3). This occurs on all signal levels and does not appear to be clipping. This can be reproduced and identified most easily by recording the Jack output with Audacity (also tested with other jack recording applications) and comparing the spectrum of the original and recorded signals. The spectrum indicates that the full bandwidth is present, but additional frequency content has appeared. This also occurs when dithering is enabled in jack. Sounds like re-sampling aliasing issue - or perhaps an internal filter variable scaling problem. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

What relevant code changes are there from 1.0 to 1.1.32?
http://source.winehq.org/git/wine.git/?a=log As a general rule, you should always test the latest development version, not a year and a half old release. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

The attached sample is an example of such audio distortion. It sounds like a badly compressed MP3. Source is "Jesus Christ" by Brand New, played using Spotify. http://www.fileden.com/getfile.php?file_path=http://www.fileden.com/files/20... -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
