Import audio with Markers (BWF)

cmodica · Unread post by **cmodica** » 25 Oct 2022, 17:35

It would be useful to be able to import into HH an audio file containing markers in order to be able to use these markers in a sampler.

Example: I put markers at specific moments of an audio file in Reaper. I then export this audio file with the Markers only option in the BWF menu.
When I import this file into an HH sampler, the markers are present.

Thank you.

What I do is save a preset file created by a preset manager module associated with the sampler player within the same patch . This preset file contains the markers and any other informamtion contained in the patch. Then I load both the audio file into the sampler and recall or read the saved preset file. I don't think there is such a way to embed markers into audio files, Markers are created by the sampler PLAYER and are just that, markers , they are not any kind of information that can be contained within an audio file, if I'm wrong please correct me.

BWF looks to be able to embed markers so maybe Senso would be able to import them. Maybe we could have a look on this.

Forgive my ignorance... What is BWF?

Yes, I think it should be an interesting improvement.

Ignorance is when you don't ask for information about what you don't know yet.

BWF is Broadcast Wave File.
These are metadata that are written with the wav file. This can be timecode, track name, markers, etc.
BWF data are very much used by film sound engineers, but not only. There can be very useful.

Hi!
I did that with global arrays, that might help.

It's working but I still didn't figure out where the global arrays files are saved in my computer !

Hi,
I improved the patch with using some scripting.
Now .mkrs files are save along the wavefiles (makes it easier to retrieved)
enjoy !

Thank you for your work oli-lab.
I can’t test because i am far away from my studio this week.
But my question was not to export segments from Usine. But to import in an Usine sampler a wav file with markers inside it. Markers are write in the meta data of a BWF in Reapers for exemple, or an other DAW.

Hi !
I know my patch doesn't answer your need, but can offer an alternative before something else comes out !

can you send a file with BWF via wetransfer so I can have look at the chunk inside it and see if it's easy to read the BWF infos ??

Cheers

Thank you Olivar.
I will send you a bwf file as soon as i will come back to my studio, next week.
Thank you very much.

Hi !
I had a look in the SDK and nothing can read the BWF data so far.
I made a BWF file with reaper and trying to localize the chunk.
so far I managed to pin point the list of markers at the end, as well as their position in samples.
Need to get some other datas as the total number of samples and I should be up and running.
Mind you it's a side project, so be patient !

Cheers

Hi,
It was raining so, I did some coding :

will be in the addon soon

not finished yet but here for you to test it.

only the markers array output is working

I'm planning to get the name of the markers, that could be handy to select markers by name

the metada output would be to read comments from the BEXT chunk (comments, originator, loudness, etc... Maybe too much work but could be interesting

tell me !

cheers

Thank you very much Olivar.

But i can't test your patch because i am on Mac OSX. The file "Oli_Lab_BWFdata.usr-OSX64" is not in the zip package.

Argh !
sorry for that,
I'll fire up the Mac mini asap

Do you use Wav or Aiff ?
so far the module only works for Wav with BWF data in it
it is differently organised chunkwise form wav to aiff and I need to make a different logarithm.

cheers

I use Wav.
thank you, very much.

Unread post by **oli_lab** » 07 Nov 2022, 15:57

Ok,
it will be wave only then
I managed to get the name of the markers, if any.
the Bext chunk is not very useful, I'll skip it for now.
MAC Os version will be ready as soon as I managed to update the Mac Mini

cheers

Hi,
the BWFdata module is in the oli_lab_pack module
You need to remove the old one before downloading it
there's a demo in the examples folder.

cheers

Thank you, it works.
You are a master! Thank you so much.
This pack is a fantastic resource for HH.
