BPMer + AccuBeatMix = perfect parties

AccuBeatMix is the natural complement of BPMer, an automatic BPM detector.
Use BPMer to sort your tracks by BPM, optimize start/stop times and/or adjust track volumes automatically, then mix your tracks in iTunes with AccuBeatMix.

Beat-Matching ≠ Crossfading

Cross-fading tracks with random start/stop times can be ugly, even if the tracks have the same BPM. Trimming iTunes to Achieve proper beat-matching is a pain, but AccuBeatMix does it automatically for you. Check our demo below!

Tips & tricks

• Pre-process your play-list with BPMer (included in the license, download separately). BPMer analyzes each track and optimizes start/stop times so the beat never fades.
• For best transitions, crossfade between tracks with matching or close tempos ("BPM"). BPM is not displayed by default in iTunes. To display BPM information, check Beats Per Minute in View>View Options.
• Do not leave iTunes' track information window open while playing - this would prevent AccuBeatMix from switching to the next track.

Questions & Answers

Q: I already own a license for Ask the DJ or BPMer. Do I need to pay for AccuBeatMix?
A: No. AccuBeatMix is already yours and will be activated automatically.

Q: How can I uninstall AccuBeatMix?
A: Remove the file named AccuBeatMix from Macintosh HD → Library → iTunes → iTunes plug-ins.
