I am hoping to switch to the VLC library, as it plays back every format and also has rate control! I use the MBS audio foundation tools on the Mac version - and it works great (although i cannot change the input source, or set the Vomiter for recording and Christian obviously is too busy to help out much his customers). I have to this point been using the media player and it’s speed feature to playback audio… it often works… but there is a 1 second silence before it changes speed. My software uses recording, playback and rate controls.
This is for my windows project… I have the MBS plugins.
