Automatic BPM detection for FLAC

But it doesn't work with Flac & it writes to a text file. There needs to be something more integrated that write directly to the database.

But for jogging a static BPM value (calculated over the whole song) is enough I would think. And for that you can use the MixMeister BPM calculator.

Build in BPM analyzer was promised a long time ago, but I assume it has since dropped on the priority wishlist.

Na i don´t think that only DJ´s are interested in this function..
I am using the BPM field to categorize music for my sports,
like Jogging or Spinning ...

well i think i push this thread up again...

I really would like to see a real BPM counter (calculator) in the player display
with the abillity to save the result in the played file by pushing
a button...
For me, i don´t need a script to proccess "all" files,
beause automatic BPM counting doesn´t work well all the time...

I don´t understand that this function isn´t build in already, because
there are cheaper tools or freeware mixers who can show BPM's
like "MJ Studio" or Mix Meister...

In case anyone's still interested, here's the solution I finally used.

1) Create an auto-playlist that lists all tracks without BPM
2) Convert all files from FLAC to MP3 at the same location. I used 96k mono files to save space.
3) Run MixMeister on the whole directory. This calculates BPM for the new MP3 files & writes it in their tags.
4) Open the 'Duplicate Titles' node. Use a script to copy the BPM field to the FLAC entry.
5) Delete MP3 duplicates that are no longer necessary.
6) Defrag.

Thanks to Teknojnky & Lowlander for suggesting this workaround. It's a long way round, but is fully automated so I can just leave the PC to get on with it.

The script I used is from this post. I just hacked it to use the BPM field rather than the ratings field.

darn? i don't know then that works for me.

OK, tried that....they don't work.

why not just go in to the scripts forum's all script thread and get the one in there that makes adding bpm's to the songs for all songs in your lib simple.

psyxonova, made the script his should work for you. but if not i had to adjust his to work on my computer so it might work for you.

try his first it might be easier then my redo of his which is not to much of a redo just an adjustment for my win98 computer.

but get his first version of the script before you try mine.

Any BPM projects on the horizon?

by **Teknojnky** » Wed Mar 15, 2006 12:28 pm

MM doesn't calculate BPM at all, so maybe you could contact the mixmiester people and see if they would be willing to support other file types.

by **Lowlander** » Wed Mar 15, 2006 12:16 pm

It was suggested as workaround as there is no solution currently and it seems a solution might not be available in the near future. And the problem it seems that MixMeister doesn't calculate BPM on Flac.

Converting every file to mp3 soley in order to calculate the BPM seems like overkill. BPM is a property of the audio, not the audio file format. The MixMeister app must decompress the mp3 in order to find the BPM of the audio content.

This comes back to my original wishlist request. I need something that can detect BPM of audio from any source format.

I have no problem with doing a bit of scripting. Perhaps the best solution is to make a script that converts the flac file to an mp3 snippet, calls the MixMeister app to insert the BPM tag, copy it to the MM database and delete the file. Still a bit of a work-around, but it's all automatic that way.

Can the MixMeister app be called from a VB script? If not, there is still a strong case for a generic BPM plugin.

That was me, BTW. Thought I'd logged in...

There is no such project at this point.

You'll need some external application/plugin to calculate the bpm value. This value then needs to be save to the library and tags which can be done with scripts.

Teknojnky's method might work. MediaMonkey sees the files in the library and the VirtualCD as one file. So saving to virtualCD as mp3 might do the trick. You might want to try this method.

Another way would pretty much do the same. You'll need to convert the flac's to mp3, calculate the bpm and use a script to copy the mp3 bpm to the flac files. If you keep the same names it shouldn't be that difficult to code.

The question is if you could add conversion to a script so you could have the script do the conversion. Then either the script could call MixMeister or you'll have to do it manually if MixMeister doesn't support it. Have the bpm value calculated. Then update the library (or read the id3 tag) and get the bpm value. Save this to Flac version and delete the mp3. This all together would not be a simple script.
