New db field - BPM

[R-Hawk]

Not sure if there is a thread already on this in the forum, but thought it would be interesting information to know.

 

The BPM of a tune is a fact, not something subjective like a record's value or what someone thinks of a tune.

 

Admitedly, it's a big job to do - but could be done alongside adding soundclips, using a BPM counter, or software.

 

For people using the db as a resource for finding records of a certain speed, I think it would be very useful.

I don't see why we shouldn't have it in the database but I don't think it will be a priority to collect this information.

 

If people are happy to do it then they're more than welcome to provide us with BPM counts. I think it'll be a while before this info would be implemented on the live site, though, there is much more to add before that

ooh neat idea & would help dj's, but that's tons of work...

 

a lot of times, artists stick to their preferred bpm (a lot of danny c stuff hangs around 175/180 while spirit could be 170 etc......

It didn't take too long! I was using a key-tap style bpm counter, so it isn't as precise as one that you would route through a mixer.

What about tunes that have a BPM that changes? There are a few!

[theorie]

Totally pointless IMHO :smile:

[Jamie Dubs]

Cool idea, if for no other reason than to map out artists' favorite BPM, or draw some cute graphs of trends (i.e. west coast stuff getting quicker over the last few years, the initial speedups from hardcore -> ragga -> etc)

 

I've used the SSL BPM analyzer to get BPM data on tons of tracks, and it tends to be almost perfect. Is there an RPC interface to submit data to RDB, or do you have to enter this kind of stuff manually?

WARNING WARNING WARNING WARNING

 

There are a LOT of programs that use a calculation routine that's COMPLETELY WRONG!!! The Behringer BPM counter's a good example of a piece of hardware that just sucks...

 

There are 2 proper ways:

1. Count the number of beats in a minute (duh...)

2. Count the time it takes for a number of beats, then calculate how much it would be in a minute. The longer the time you're counting, the more precise the BPM should be...

 

There's (at least) 1 wrong way:

For each SINGLE BEAT calculate the speed, and take the average from your new count and the previous total. Why is this wrong? Try this:

Beats: X---X---X---X--- (the X-es are the beats)

Now tap in: X---X-X-----X--- (so offset 1 beat). If you get a count that's a lot higer than normal... they're using a wrong calculation routine...

 

So therefore I'd still wouldn't trust supplied BPMs (Behringer calculated BPM's for example are usually about 5 lower than proper ones).

 

so it isn't as precise as one that you would route through a mixer.

 

If the "beat match" led on my old mixer is anything to judge by it seems to get confused when it doesn't hear a kick every time. And even progs like VirtualDJ screw up BPMs quite often (even on club tunes).

I'm with Theorie, waste of time. One of those pieces of information that we might collect for a few hundred tracks but most will never get done and just leaves a gap in most database entries.

 

I think there are other priorities - the user submitted automatic creation of releases the first one! That would free up Thijs to concentrate on more site development.
