bpm issue with mp3s

I'd say it's the vinyl fluctuating in BMP. Vinyl can be a bit all over the shop due to the way it works. 

yeh cool had a feeling it was related to that.

thanks Morgo

@thedom > Did you run the files through Rekordbox first, prior to playing them on the CDJs?

@Gavin - yes i did, i ran mp3val to validate files, then ran them through recordbox like i normally do.

@thedom > And under which mode did you analyze (dynamic or static)?

@Gavin > I would be on whatever is the default mode! Is this a preference setting to change mode ?

When recording vinyl to a digital format, I recommend the following:

1.  Do not use slip mats.  Use the rubber mats that came with the record player.  Slip mats can give you uneven friction with the platter.  This may result in fluctuating tempo during the recording.

2.  Use a high-quality home stereo with phono inputs....  do NOT use a DJ mixer.  DJ mixers are designed for blending multiple audio sources.  But for the best quality playback of a single source, you should find a higher quality preamp.... preferably something with no EQs or other processing.

3.  Once you have recorded the vinyl, I would suggest running it through Ableton Live to warp the track to a perfectly constant tempo.  Then render the music to a new WAV or AIFF file.

4.  I would suggest not compressing to MP3, but if you must do this.... then use a high quality encoder and stick to 320k and don't use VBR.

Normal would be the default setting. Dynamic takes into consideration more fluctuating BPMs (ie where they aren't constant).
