So I created some actions to fix those, maybe someone else would find those to be useful as well In my personal experience Mixmeister software is not very good on producing accurate BPM or Key results. Results: 1] Instead of foobar's range , I came up with BPM range from 75 to 2] Five files had exact or almost exact BPM as they did in foobar; and remaining twenty one tracks came with higher values 3] Twelve tracks came with exact or almost exact BPM as they did in MixMeister; and of remaining fourteen tracks eight came with higher values and four with lower 4] No FLAC support.

Results: 1] Instead of foobar's range , I came up with BPM range from 75 to 2] Two files had exact or almost exact BPM as they did in foobar; and remaining twenty four tracks came with higher values 3] Fourteen tracks came with exact or almost exact BPM as they did in MixMeister; and of remaining twelve tracks nine came with higher values and three with lower 4] Sixteen tracks came with exact or almost exact BPM as they did in Abyssmedia BPM Counter; and of remaining ten tracks three came with higher values and seven with lower.

And that is, why they did include that sort of correction as an additional manual option in foobar So the process is automatic only in theory. Because I would have to listen and possibly click a proper action for manual evaluation after the automatic one. But from those four tests I can see now quite clearly, that this is getting me nowhere near, what I need. Instead of making things easier, speeding them up and making more accuracy in categorizing, with [automatic] BPM I would only produce unknown amount of errors.

And on top of that, there is also issue of FLAC files, not processed by every software. And also what is important here, each of those four programs have listed as slow [no higher that BPM] at least three action oriented tracks [out of twenty six]. Alternatively: I could add four BPM values and divide the result by four [and even making an action for it]. I think easier would me to send you back the values, not entire files Every algortithm can produce some errors and inaccuracies Results: 1] Instead of foobar's range , I came up with BPM rang from 80 to 2] Five files had exact or almost exact BPM as they did in foobar; and remaining twenty one tracks came with higher values 3] Sixteen tracks came with exact or almost exact BPM as they did in MixMeister; and of remaining ten tracks four came with higher values and six with lower 4] Seventeen tracks came with exact or almost exact BPM as they did in Abyssmedia BPM Counter; and of remaining nine tracks four came with higher values and five with lower 5] Seventeen tracks came with exact or almost exact BPM as they did in Rapid Evolution; and of remaining nine tracks four came with higher values and five with lower.

So, If one were to assume, that 4 out of 5 same or similar results from this test should be viewed as the correct value [ignoring the, sometimes, completely different fifth one], it gives 16 out of 24 automatically rated tracks. And from the remaining 8, there are 3 like a split [2 for one value and 3 for some other value].

Although in this case the test was done only on 26 pre-selected tracks, it also produced some accurate results and some evaluations similar to BPM value detections. But at the same time it also made some weird choices. And in one special case, it showed clear symptoms for unacceptable inaccuracies. It was the case of an original mix, which had energy valued as 4, and a simple remix of that track with a louder beat, which had a value 6.

Both of those tracks have the same structure and length, ad this remix is more like a mix, because the changes in music are pretty small. And how did those two very very similar versions of one track ended up among those 26? Well, foobar valued both of theme as 80, so there were selected by me on the basis of being slow [under ].

If you didn't adjust the beat-grid, you didn't really change the BPM of the track. I manually set my bpms in iTunes. A website or app. Not Rekordbox. But I dont think it has timestretching capability, its more of just an audio editor. You would have to do a search on it and find out.

There are plenty of web forums just for Sony users. Ableton Live can do it no problem. PM me if your interested in a copy of it. You don't need to change the BPM of those mp3 if you are going to be djing.

If you mix with a PC, you can adjust the difference on the fly, that's called
