Troubleshooting : Multi-channel Audio Files
30 - 773
Playback Stalls Warning
Playback Stall messages are triggered by access delays impacting the VS3, resulting in audio drops while preserv-
ing the synchronization of the Tracks. In the latter case the stall may also endanger the integrity of the synchroni-
zation between Tracks being recorded.
Record Stalls Warning
The Your Recording may be at risk warning indicates that the Destination Media Drive performance may be
insufficient. If so, we detect it and recommend that you change the destination media drive or optimize it.

Multi-channel Audio Files
Wave, Broadcast Wave, AIFF or SDII multi-channel files are seen as mono files by the Pyramix Media Manager
unless their file names conform to Pyramix requirements.
Audio File Formats
Some audio file formats (like Pyramix native format, PMF and OMF) embed the Track/Channel number(s) in the file
itself. In this case, Pyramix recognizes the Track as mono, stereo or multi-channel without problem even if the dif-
ferent audio Tracks/Channels of these files are actually stored in separate files.
Some other formats (like Wave, Broadcast Wave Format, AIFF or MacIntosh SDII) do not keep this information in
the file itself but in the filename. Unless the correct naming convention is followed, Pyramix will see files in these
formats as individual mono, regardless of whether they are part of a stereo pair or multi-channel recording.
Broadcast WAV Files
BWF-P means polyphonic. I.e. multitracks within the same file
BWF-M means monophonic. I.e. one file per track
Pyramix Requirements
In order for Pyramix to recognize that separate audio files in these formats are actually part of a stereo or multi-
channel recording, Pyramix requires the following naming convention:
The filename of the different Tracks/Channels must be the same except for one section containing the Tracks/
Channels number as 3 digits surrounded by _## and ##_. For example: MyStereoSound_##001##_.wav and
MyStereoSound_##002##_.wav are seen by Pyramix as a single two Track media named MyStereoSound.
Other systems, the Zaxcom DEVA portable recorder for example, do not use the same convention. They may name
the files they produce in this fashion: MyStereoSound-1.bwf and MyStereoSound-2.bwf. These files will be rec-
ognized by Pyramix as two mono media files.
Solution
MultiFileFixer is a small ‘tool’ application that automatically renames all files in a given folder and sub-folders,
that fit selected parameters, to follow the Pyramix convention.
In a normal Pyramix installation the MultiFileFixer application can be found on the Windows Start menu:
Start > Programs > Pyramix > MultiFileFixer
Clip Display Problems
No Waveform Display
Symptoms
Files are dragged into the Timeline from a mounted folder but no waveform is generated. Manually invoking Gen-
erate Waveform doesn’t work.
