Hi, Ben, I only really know two audio programs, though I have used a few others. The two that I know are Samplitude (and therefore most of the features of the higher-end Sequoia) and iZotope RX 5 Advanced. In Samplitude this is a no-brainer. Samplitude works in Virtual Projects (VIPs) where the timeline is a separate file from the audio WAV file. You can set up, for example, a four (stereo) track VIP and record in four cassettes at the same time. This, of course, assumes that you have four cassette machines. Then you need to create four separate VIPs (one for each cassette) and bring the WAV file into it. Then, there is an option to select how "silence" is defined and acted upon. Please see a screenshot of the appropriate window. http://bit.ly/1I8KL1f From there, you can select on the Export window that you make a file for each marked track separately. You can also name the tracks and that becomes the filename with or without an optional numeric prefix (the track number). The export can be WAV or MP3 or several other formats, including FLAC, I believe. I hate to suggest that you change DAW software, but I got into Samplitude in 1998 or so and kept upgrading. When I bought WaveLab6, I was most disappointed on almost every front comparing it to Samplitude and I never bothered to update it. I needed it for a project as the client couldn't open BWF files created in Samplitude. It turns out to have been subtle errors in both programs, but Wavelab was the only DAW that couldn't open the files. It was fixed in a subsequent ver 6 update. The version comparison of the three Magix Audio pro products is here: http://www.magix-audio.com/us/samplitude/version-comparison/ You are lucky! The price of the Samplitude product line has dropped about 40 % recently. I use the suite, but the restoration products, while good, are not as good as iZotope RX5 Advanced ($1200, sometimes on sale for $1000 and also as part of a bundle, but it's not good for the editing task that you suggest).
