Subject: [ecasound] request modification to the .ewf file format

Hello,

I wish to request modification to the .ewf file format such that you may,
if desired, specify offsets in frames rather than time-in-seconds. Can
ecasound be told to seek to a partidcular frame in a file and start
there? I am seeing rounding problems because I wanted to go to frame
100038656 and I wanted it to play for 53678848 frames. The math tells me
this is 2084.1386666667 seconds.

When ecasound rewrote this as cs-save, it converted to 2084.139, causing
an offset of 16 frames. I recommend ecasound use something more exact for
time offset than time_in_seconds since it is shown here an error can be
made due to sloppy rounding.

Also I have noticed that if you use -y:n then setpos, rw, and fw, lose
this information and you lose sync with your audio sources. If I
converted to .ewf instead, would setpos, rw, fw, etc work correctly?

I currently have this one source starting at time 0 and all the others
starting at 2084.136666667, so I cannot do rw fw or setpos because all the
other sources go back to time relative since 0 instead of time relative
since 2084.6666667.

Comments appreciated.

_J
