From Tagtraum Industries:
BeaTunes automatically determines BPM (beats per minute) and key and looks up track metadata using acoustic fingerprints. It can import lyrics and determine their language automatically and categorizes songs by their sound color. BeaTunes fill in the blanks and help you while DJing at your next party. It can automatically determine BPM (beats per minute) and store the result in iTunes. It detects tonal key and sorts existing playlists so that matching songs succeed each other.
What's new in this version:
Moved from QTKit to AVFoundation on OS X.
Fixed possible crash when analyzing AlbumReplayGain on Windows.
- Application crashed nearly every time, but worse than that, it crashed my laptop several times, resulting in a blue screen of death in Windows 7 - While it integrates with iTunes, its "color" and "key" information isn't accessible in iTunes - Has no way of accessing and analyzing protected music (DRM)
Seemed like a good idea, but unfortunately, it is a very, very unstable product. I wouldn't mind if it only crashed with no impact to other applications, but this IS NOT A WELL BEHAVED, WELL DESIGNED APPLICATION! Luckily, it didn't corrupt any of my music files (at least there isn't any evidence of it yet), but any application that seems to directly access protected memory is a serious NO NO.
I was searching for a BPM and Key audio application and I will say this. It's BPM analyzation seemed much more accurate than some other apps (namely VirtualDJ).
Also, as with all other applications, if you have any protected music, it cannot analyze them either.
Is usually wrong on BPMs. Screws up most of your metadata in iTunes
This is a terrible program. Terrible. I'll never get back the time in my life it took to fix all the metadata in my iTunes collection. I bought the program to make playlists for running, but it didn't do that right either. The BPMs are all over the place. DO NOT BUY.
Simple to get started, inexpensive to purchase the full version, great for people who spend time organizing their iTunes music. I stumbled upon this while trying to make a mix cd - I needed something that would help me find the Beats per Minute [BPM] of my music. It will also make finding gym music playlists easier, imo.
It runs a little "heavy" (Not sure how to describe it other than the results of a click are not always immediately registered). That could be because I have over 4500 songs it's trying to analyze....
beaTunes comes with a 'Library Inspector', which goes through your iTunes music collection and finds discrepancies (wrong genre, typos, missing files). The kind of stuff that just happens when you (like me) have 25,000 songs and more. It then offers to clean things up for you. You have to confirm every change, which is good since there were some false positives.
Other than that, it analyzes your library for similar songs. Once the analysis was done (one time effort), it actually created some pretty good playlists for me.
All in all a very useful tool for anybody who likes to keep his library neat and is tired of creating manual playlists.
Analysis takes a while. The automatically created playlists aren't necessarily perfect.
