Another useful is if you want to post up a comparison to a forum such as this one. A thread such as “AC30 reissue vs original” can be really enhanced with a couple of clips to link to, yet it’s not worth the hassle of converting a recording and suchlike. With this, just record the two samples and upload the files to a suitable host. Quality’s perfectly good enough for the task. I’m hoping to do something of the sort soon.
