Slice using computer?


I was wondering - could you slice audio files on a computer for use with the 301? I think at least Morphagene allows for this, was wondering if the 301’s slicing format is such that it’s possible.

No plans to do this at the moment, mostly because AFAIK there is no widely-adopted open and documented file format for sliced audio. REX is not an open format by the way. I could be wrong though, so if you know anything please let me know.

Thanks! I don’t know of any easy solutions - I think the Morphagene way was only available using s pretty specific set of audio editors (or just one?).

Anyhow, I think having good options for slicing within the 301 would be the best scenario. Was just wondering whether there’s prep work that can be done on my computer.

I am super-surprised there is not a standard xml format for this type of data yet. Maybe you need to be the thought leader and establish one, @odevices!

Oh hey.

This looks interesting! Have you (or anyone else) tried using it?

Have not but will download and give it a shot. Still very surprised that nobody’s bothered going down this road.

I asked recently the same question of 1010 Bitbox and discovered that the format is in a proprietary XML. The information’s easily accessible there, but not to any music software!

I’ve been very surprised over the years at the lack of standards regarding markers and metadata in audio files and the difficulty of sharing them with the files.

I produce long form audio documentaries for radio and markers are incredibly useful to find snippets of audio dialogue in sometimes hours long audio files. It’s almost impossible to do when using different softwares and so paper edits still reign. There’s a cross platform software developed explicitly for radio production (which I shan’t name) which doesn’t even retain timecode information in files once cuts are made in them. That is to say, as above, one has to go back through the transcript to find the timecode at which a cut was made! I share jj.kidder’s very surprisedness!

I think it was Reaper which was the only software which made markers available for Morphagene.

It occurred to me that researchers that work with speech (linguistics, speech pathologies, speech recognition, and so on) have pretty sophisticated needs when it comes to labeling audio. It might be worth looking around there since the barriers to sharing are lower in the scientific communities.

For example, here is a program designed for labeling speech (it even draws pitch contours) but works on any kind of sounds:

The output is a text file.

I tried it out. It only crashed once. Haha.

Hold on. Audacity has something called “Label Tracks”.

Just tried quickly adding 3 labels to an mp3 file:

Then exporting the label track yielded a text file with the following 3 lines:

4.478823	6.422177	test
9.413120	11.083190	test2
14.180410	16.366683	test3

Looks like we might have a serious candidate…


Yeah, Praat was one I was thinking of, but it’s written in Java, is it not?

i.e for a format to load into the 301? The issue often with markers is to ensure that they stay in the same place on the audio file, no?

I still have a copy of ReCycle somewhere but haven’t used it since, well… the days of Reason! That seems like an awful long time ago… it really is the biggest tragedy that Propellorheads went so hardline with their copy protection and encryption as this would have been a world dominator by now if they had just chilled out a little bit and been more open. They certainly lost a customer here precisely because of this.

I just took a peek at a .slc file from the ER-301 and the information is only really machine readable i.e. not stored as XML.

Found this round up of the different slice file formats

I tried to look at Translator, but i couldn’t work out if it handles slicing or not, it’s a bit weird and the website a bit broken.

Vice seems popular, but I’ve no idea what export looks like!

Oh wow - just seen all this activity now… maybe what I wrote is no longer relevant!!

Audacity looks like win!!

Nice find, I had no idea it did that :smiley:

Best thing is, I already have it installed!!

Here is a huge software suite from McGill for music research:

The timecodes in the Audacity label track are in seconds from the beginning of the file. I don’t see any problem with loosing time sync with that. Do you?

I used that in the abovementioned translation to a different file type for the ABC here in Australia to move from Logic to Steinberg’s WaveLab and it worked very well…and was surprisingly current with format versions despite the archaic website…can’t be sure about slicing 'tho

That’s right. It is literally just binary-packed C structs at the moment (the fastest read times). I knew I would have to revisit this in the future so I made it quick and dirty thus easy to throw away and redo.

You’re WAY better qualified than I (I’ve not yet my hands on a 301!) I’m just thinking of relativity in terms of trimming, i.e. if you move a start point the text information isn’t dynamic, so it may shift the position of the marker unexpectedly?

Did I explain that sufficiently?
