Hi ! Thanks for the replies on slowing down audio. I would like to build an audio file using several other audio files, preferably with some 2-4 seconds silence between them. Actually this is to upload to youtube a series of songs as one single file, that does not need the use of a playlist. The files are currently in wav (Ardour export) and ogg. Which tool can be used to construct such a file ? Very quickly I'd think of using Ardour to put all the files one after another and then export the result, but that seems overkill, and possibly taking more time to do. There has to be something more like a 'tool' to do that. Suggestions ? Cheers. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
