Bought this for my dad to convert his old tapes to put on CD.
Whilst the device itself is pretty good (except that it lacks a tape counter for you to know where abouts you are on a tape), the EZ Tape Converter software is a bit lacking.
It's supposed to split tracks for you, but it didn't work and there are no settings to give you any degree of control at all.
Forgetting the software though, the device itself registers itself as an audio input device, so you don't need a cumbersome tape player and audio leads to plug it into the MIC/AUX IN inputs, etc, etc.
If you have a wave editor, eg. Adobe Audition - or probably even the sound editor you get with it, Audacity - and you have some experience in editing digital audio waveforms (not too hard to pickup if not) you can use this to record an entire tape, as the wave editor software will pick up the sound via USB and it will appear in your editor as an audio waveform.
Then you just need to split the wave file you get into individual tracks (you can clearly see the breaks between tracks) and save them in whichever format you want.
So all-in-all, worth the money for the convenience of the hardware, but just don't expect much from the supplied software!
