Donaldson R F Join Audio Files
Merge songs, voice clips or recordings into a single file. Add the files, put them in order, choose a gap between them and save.
Joining audio files
Add two or more files (you can choose several at once, or add more later), then use the arrows to put them in the order you want and the × button to remove one. The files are joined end to end. If they use different sample rates they are brought to the rate of the first file, and if some are mono and others stereo, the mono ones are played on both sides.
A tiny fade at the edge of each file stops a click where two pieces of sound meet; choose None for a strictly gapless join of tracks that are meant to flow into each other. Because everything is held in memory, the total length is limited (see above). To trim a file first, use the MP3 cutter; to smooth the ends of the result, fade in / fade out.
