liveBPM - Beat Detector

The accuracy/precision of this program is pretty bad :(

I’m a new user to Live BPM. After working with it for many hours now, I’m happy to say it works easy and seamlessly. The one enhancement I would suggest is: Adding a regular Metronome feature that you can set at the beginning of each song on stage(to begin the song) then display the beginning tempo to the ongoing tempo during the performance. Not sure if you can do this. It would definitely be an enhancement.

This is for anyone working in professional DAWs…Pro Tools, etc. I was dealing with a click track that had undergone a move in tempo but that move had been applied via the pitch shift algorithm in pro tools putting the tempo quicker but not precisely on any whole number (in the likeness of tape machines). The music and this new click were in perfect sync but the session grid was still in the previous BPM. LiveBPM saved me a ton of time by getting me in the right “zipcode” where I could then begin going granular with the BPM in the session. After starting playback of the click, liveBPM instantly honed in on 156.81 BPM (click was subdivided into 8th notes) and then only occasionally moved to .82 or .83 but stayed locked on .81 90+% of the playback. Since the BPM / grid of the session was defined in quarter notes, I cut 156.81 in half and that got me to 78.4050 (Pro Tools has BPM defined to 4 decimals). At that setting the old and new clicks were extremely close. A couple more fine adjustments and an a/b comparison of both clicks on playback rendered no discernible difference at a final setting of 78.4056. The only way to detect any drift between the two clicks was to microscopically zoom in visually on each to see that a tiny amount of drift was beginning to happen in the final measures of the 6-minute song. My only wish would be for a pro version of liveBPM to exist with detection to 4 decimals to match pro DAWs but I can certainly understand the market for that being most likely small. I’m most grateful to have located this app. Thank you for developing it.

I wish I could set the full range to a narrow range. We want 110-120, so wish I could set the entire graph range to 100-130 or so.

Forcing you app to run in landscape mode is a PIA. Yes, if you operate in landscape the controls are similar to portrait mode but it’s awkward and what in this app requires the width? Stumble over this whenever I use it.

Love this app, use it almost every session! Daniel is there any way to feed audio into the headphone port to detect beat? An option for detecting 3/4 time would also be amazing, thanks!

How do I get it to work

A friend brought his to a session, and I found it useful and download my own copy. It works when I run it. But the app switcher on my iPhone 12 Pro (iOS 16.2) doesn’t work within live BPM. It works with all my other applications. The only way I found to exit is to shut down my phone and reboot. Not good. I found no way other than Facebook to contact the creator Daniel Bach. Not so good for those of us that choose not to sell our soul to Meta. Updated: 4/5/23 App developer Daniel Bach offered this help: “the app is closed by swiping in the orthogonal direction, like all apps running in landscape mode”. This is the only app I have that runs only in landscape mode, and a Google search didn’t offer much insight. But with experimentation I found fix. A greyed out bar appears at the bottom of the landscape mode screen. One upward swipe turns the bar from grey to white, and a second upward swipe get you back to the Home Screen.

This app will not work on my iPhone. It will open and not respond to anything and then you can’t close the app without rebooting your phone. I feel like I was scammed out of the few dollars that this app cost me. Don’t buy this app! It doesn’t work.
