Re: [Osalp-dev] Fwd: Asynchronous playback?

[Robert P. <Rob...@am...>]

Perhaps I am doing things incorrectly. In your example code I noticed that =
you just copied the config from the input to the output. If I open two =
inputs and use the config from the lower sampling rate input source as a =
parameter into the output then all inputs play at that lower rate. This is =
why I thought I needed to do some manual conversion.

Attached is my source code for your perusal. Its just a mainline hack at =
the moment until I test all the functionality I will need for the real =
classes.

Thanks!

Your right it will send the current file position to both files. I need
to add
something to the library that will allow one to either delay one channel
or allow
a file position adjustment of some sort. Let me think about this for a
couple
of days.

chipmonks. :) Do I use aflibConverter for this?

In an audio chain you would use the aflibAudioSampleRateCvt class.
aflibConverter is
a low level class and is difficult to use. When you mixed the two audio
files
together it should have adjusted both to the highest sample rate. It
would have
automatically inserted an aflibAudioSampleRateCvt class. There might be
a problem
when you add a channel dynamically. Please let me know if you did this
dynamically
and it did not work. If so it is a bug and needs to be fixed.
