Hi guys, I'm new to all thing foo and am currently clambering up that learning curve to get things set up as I want them. Loving it so far. Wish I had made the switch a long time ago! Anyway, first off, let me thank fraganator for all his hard work. And secondly, give you all some results from a little playing around I've done. I used the two Lily Allen albums to test. No reflection on my musical tastes, they were just the first thing I thought of that had varied BPM and some possible troublesome tracks. FLAC files with f00_bpm, and ALAC with beaTunes.Track Manual | beaTunes | foo_bpm | foo_bpm 1 | 2 3 | 4 5 6 7 8 | 9 ---------------------------------------|--------------|----------------------------------|-------- Smile 95.6 | 95.3 95.3 | 190 190.3 95.1 95.4 95.5 | 95.5 Knock 'Em Out 130.5 | 64 128 | 159 159.6 159.6 159.9 64 | 64 LDN 100.5 | 50.1 100.1 | 100 99.6 99.6 100 100 | 100 Everything's Just Wonderful 157.7 | 79 79 | 79 78.7 78.7 78.9 79 | 79 Not Big 102.6 | 51 102 | 102 101.7 101.7 101.9 101.9 | 101.9 Friday Night 128.9 | 63.8 127.6 | 127 127.1 127.1 127.5 63.8 | 63.8 Shame for You 74.3 | 74 74 | 147 147.5 73.8 147.9 74 | 74 Littlest Things 82.7 | 82 82 | 82 81.7 81.7 81.9 82 | 82 Take What You Take 100.4 | 100 100 | 100 99.7 99.7 99.9 100 | 100 Friend of Mine 82.6 | 164 82 | 163 81.7 81.7 81.9 82 | 82 Alfie 120.3 | 120 120 | 120 119.5 119.5 119.9 120 | 120 | | | Everyone's At It 117.1 | 117 117 | 78 116.6 116.6 116.9 116.9 | 116.9 The Fear 134.2 | 67 134 | 89 133.5 133.5 133.9 133.9 | 133.9 Not Fair 121.7 | 121.5 121.5 | 121 121.1 121.1 121.4 121.4 | 121.5 22 131.2 | 131 131 | 75 130.5 70.8 130.9 65.5 | 65.5 I Could Say 124.8 | 124 124 | 124 123.6 123.6 123.9 62 | 62 Back To The Start 140.3 | 70 140 | 140 78.6 70.0 70.1 70 | 70 Never Gonna Happen 71.9 | 71.5 71.5 | 142 142.5 142.5 142.9 142.9 | 142.9 Fuck You 130 | 130 130 | 129 129.5 129.5 129.9 65 | 65 Who'd Have Known 85.2 | 84 84 | 84 83.7 83.7 83.9 84 | 84 Chinese 72.3 | 143 71.5 | 95 95.1 71.3 142.9 142.9 | 142.9 Him 96.3 | 96 96 | 191 95.7 95.7 95.9 96 | 96 He Wasn't There 70.8 | 70.7 70.7 | 76 76.1 75.9 141.3 141.6 | 141.3 ---------------------------------------|--------------|----------------------------------|-------- 1. Manual Tap. I use the underlying tempo. What I consider to be the head nod, foot tap, shake that arse beat that people would use. This defo gives better results when used in smart playlists. As has already been pointed out, you often need to double up, or halve the suggested BPM. 2. beaTunes, Rayshoot, auto range, highest quality, don't use online resources. This is spot on apart from the need to double/halve some tracks. 3. beaTunes. As above but with a range of 70-140 bpm. Even better results. Only "Everything's Just Wonderful" needs changing, and that's down to personal preference. 4. foo_bpm with default setting, 6 tracks are way off. 5. As above but with precision set to 1 decimal place. This is better, only 4 are off. 6. As above, with a range of 70-160 bpm. Only 3 off now 7. Next I doubled the seconds per sample and samples per song up too 20 each, and halved the FFT size to 1024. Only 1 wrong now, the troublesome "Knock 'Em Out"... 8. Fiddled around with lots and lots of small changes. Many of them fixed the problem track, but broke others. The above config, with Seconds per Sample up to 30, Min Sample Offset down to 10%, Max Sample Offset up to 90%, and Min BPM down to 60 finally gave a result I can live with. And finally, I decided to check out performance with lossy files. beaTunes with AAC .75 VBR and LAME -V0 worked well. Identical results as test 2, so no point adding them to the chart. 9. foo_bpm, same config as test 8, AAC .75 VBR. Virtually identical results. I'll forgive one or two tenths of a beat in a couple of files 10. As above, with LAME -V0 files. Same results as test 9, so won't bother adding them to the chart.Conclusion : It's looking very promising but is a bit too much like hard work at the mo. Whatever beaTunes are doing works for me. Just wish I didn't have to transcode to ALAC and back.
