This is so annoying.

I have samples and regardless of their duration (some long, some short), it's so random how Live decides to ignore the actual sample BPM and 50% of the time I have to manually click on "warp" and double click on the BPM to set the correct one again.

A major waste of time and workflow limitation when testing out many samples by key.

I don't understand why some samples, say marked as 120 bpm in a commercial pack, will (about 50% of the time) not be properly processed by Live. They will show some random value like 106.5 or whatever.

Warping mode preferences in settings seem to have no effect on this bug.

This is not Ableton specific at all. Logic does the exact same thing. I believe the .wav file has attributes which are read this way; where the file is either tempo stamped or there is metadata. Like the Acid properties of those files, as example. the first thing to check is usually to see if the sample is even cut right at the start and end points.

1.) WAV audio files can hold several metadata types. These metadata types were introduced over the years into the WAV format, which is extensible by nature. WAV is based on the Resource Interchange File Format (RIFF), and made of chunks of data. Contrary to popular misconception, adding metadata to WAV files does not break the format.

Any well-behaved WAV reader is able to handle every WAV file even if it doesn't understand all the chunks it contains, in which case it simply ignores them. The following is a description of the different WAV metadata types, and the software that support them.

can confirm this happens on some samples on FL studio too.
i don't want to have information IN THEM, just put them into the file name for fuck's sake...

 

Yes, but afaik not all WAV are "acidized" wiht meta-info while AIFF are always. So does it happen to AIFF as well?

well, let's say I have seen enough samples in Logic do this, that I almost give it no more thought. I set the loop points correctly in the editor if needed, and usually click the 2X because the majority of this results in half tempo loading of samples onto your audio channel. or I skip that, right click the sample and convert the audio into a sampler track, and set the loop points inside QSampler. I just deal with it on a per file basis as wav. AIFF are "locked" how they are, as Live Loops. I use Tracks View and wavs only (when possible) to avoid that. I do not use the FL style "Loops" features at all, mostly because of this exact subject. but I think the issue is the samples being wrong in the first place.

are you using half time smaples? where the sample maker says its 120 but in reality it is really 60bpm? I feel like that could confuse a computer... but I dont mess with samples so thats all i can think of

 

afaik wav files (originally) does not hold metadata except the INFO chunk, but as it is an extensible format info can be added and (most) programs will still read the audio correctly even if they don't understand the added chunks. with no real standard, it's all a mess

More importantly for you, again afaik, Ableton does not write or read metadata (not talking about .asd). So, the warping is done on the fly, hit or miss. For me re-warping (dis-re-enabling) sometimes work. But usually I double check loops and the rest..

 

Not half time samples, just plain and simple deep house, electronic or melodic techno 120 bpm - I've noticed it really depends on each pack and brand, so there must be some sort of BPM metadata somewhere which I'm failing to understand is it stored somewhere in the file or something.

 

Okay:

1. let's say the warping is done on the fly, how come Pack Brand 1 Deep House 120 BPM > all the files will sync perfectly and Pack 2 Deep House 120 BPM > all the files will not sync and I need to re-warp/adjust them? And worse, it won't be remembered next time I open them again, so I need to do it again each time?

2. Let's say there's no metadata (as an .asd) fine but is there a way to re-record the samples? I guess if I re-record the said sample on the fly, this time it will remember the right BPM in my instance of Live? But it's such a pain man... Is there no right-click option or something that would permanently allow us to set the BPM on this sample, FOREVER?

 

I think the only way to make it permanent to a WAV file is to acidize (save beatpoints, bpm and other meta info inside the WAV) it. Magix Acid Pro should do the job. but tahts a loz of extra work.

Live is working non-destructive and saves the data in a corresponding .asd as an extra file and not inside the WAV that remains untouched. If you always load the wav into your project, you need to adjust it every time.
Have you tested to leave the .asd files directly in the sample collection directory. The information should normally stay the same for all projects.

Or use REX files instead, they contain this information by default.

Basically what @twoheart wrote. Exept that I think Live reads acidized wav as any other wav, ignoring the Acid info. I stand by - does not read, does not write until proven wrong. ;)

True, it can even be the same pack. Sometimes it works as expected, sometimes not.. it's the same with e.g. DJ SW. I never blindly trusted the automatic beat detection.

When you tidy your sample/loop up to your liking, you can right-click and consolidate it (Ctrl+J). Then right click and choose Show in Explorer. The folder under Project > Samples > Processed > Consolidate will pop up. There all your consolidated samples/loops will pile up. It's also a way to quickly save one-shots or whatever..

It will not write info to the wav, it will make an asd.. see whether you can ad it to your workflow

 

Interesting thread…I’d like to increase it (just wouldn’t start a new one)
Tempo and pitch reducing (up and down):
I have some samples in ACID WAV and they have a very noticeable fall in their quality if they have another tempo than a project in a DAW, this is a point #1…
and the #2 is – some companies still sell sample packs in various formats…
for example:
https://www.bigfishaudio.com/Lucky-7-Funk-and-Retro-Themes

they suggest Acid, WAV, REX, Apple Loops, Momentum (just for $100)

ACID I already mentioned, but curious about REX…never had any deal with it, but heard it’s very versatile exactly for tempo/pitch/transposing
So, the question is:
the best possible QUALITY after all those manipulations –
which DAWs, plugins make it better ( Momentum is one of them)?
Is REX one of the best decisions? Which DAWs work with it (REX to WAV and vice versa)?
