![]() ![]() ![]() I would be interested to hear whether anyone else has use the Amazing Slow Downer for practise purposes. In any case, the Amazing Slow Downer costs only $45, whereas the Tascam CD player costs $150 and the Superscope PSD230 $350 and the Superscope PSD300 $600. However, I do not have access to either of these instruments. I would have liked to have tested Roni's Amazing Slow Downer against Tascam's CD-VT1 MKII Vocal Trainer or CD-GT1 MKII Guitar Trainer or CD-BT1 MKII Bass Trainer or against the Superscope PSD230 or PSD300. The time and pitch were accurate so that it could still be used for practise and transcribing, but it would be very irritating. Again the sound artifacts were obvious and irritating from the word go. It may be that the more recent versions have improved. Bear in mind that I have only version 4.16 of GoldWave (about two years old). Laced throughout the song are odes to other songs from both albums (notably Alpha). Shortly follows is a depression inducing breakdown that chills to the bone. It has a soul lifting chord progression filled with Spencer's incredible singing. It might be good enough for practise, but would be so irritating that I doubt if I'd be able to keep going for long. The song tells a beautiful story with an unforgettable climax. I guess this would still be accurate enough to transcribe, although it would be unpleasant. In particular, it seemed to create extra sounds in the deep base. The artifacts were apparent and irritating in the first five seconds. The time warp in GoldWave was second best. It might even be good enough, depending on one's tastes, for performance/gig purposes. to slow down a Music Minus One or Music Partner recording, or for transcription. The quality was certainly good enough for practise purposes - e.g. The pianos came out sounding quite different to normal pianos in that there is much longer continuity of tone (the decay is twice as slow) so they almost sound like organs. The pitch was, of course, preserved perfectly. There were very few artifacts and they were not readily noticeable. Roni's Amazing Slow Downer was far better than the other two. I then created a file with each of the three systems, with a 50% reduction in speed. To do this I ripped the first variation of Brahms' Variations on a theme of Schumann, in E b, for two pianos. I tested (a) Roni's Amazing Slow Downer, (b) the time warp included in GoldWave (version 4.16), and (c) the time warp in Audacity. ![]()
