The title is a bit confusing as open-source separation of ... reads like source separation, which this is not. Rather, it is a pitch detection algorithm which also classifies the instrument the pitch originated with.
I think it's really neat, but the results look like it could take more time to fix the output than using a manual approach (if really accurate results are required).
- emptiestplace 2y agoNo, it doesn't read like that. The hyphen completely eliminates any possible ambiguity.
- croes 2y agoMaybe added later by OP? Because there is no hyphen in the article’s subtitle. >Open source seperation of music into constituent instruments.
- emptiestplace 2y agoThe complaint: > The title is a bit confusing as open-source separation of ... reads like source separation, which this is not.
- ipsum2 2y agoThe title of the submission was modified. It you read the article it says: Audio Decomposition [Blind Source Seperation]
- earthnail 2y agoThanks for clarifying. In fairness to the author, he is still at high school: https://matthew-bird.com/about.html https://matthew-bird.com/about.html Amazing work for that age.
- TazeTSchnitzel 2y agoIs “source separation” better known as “stem separation” or is that something else? I think the latter term is the one I usually hear from musicians who are interested in taking a single audio file and recovering (something approximating) the original tracks prior to mixing (i.e. the “stems”).
- timlod 2y agoAudio Source Separation I think is the general term used in research. It is often applied to musical audio though, where you want to do stem separation - that's source separation where you want to isolate audio stems, a term referring to audio from related groups of signals, e.g. drums (which can contain multiple individual signals, like one for each drum/cymbal).
- Earw0rm 2y agoStem separation refers to doing it with audio playback fidelity (or an attempt at that). So it should pull the bass part out at high enough fidelity to be reused as a bass part. This is a partly solved problem right now. Some tracks and signal types can be unmixed easier than others, it depends on what the sources are and how much post-processing (reverb, side chaining, heavy brick wall limiting and so on)
- dylan604 2y ago> This is a partly solved problem right now. I'd agree with the partly. I have yet to find one that either isolates an instrument as a separate file or removes one from the rest of the mix that does not negatively impact the sound. The common issues I hear are similar to the early internet low bit rate compression. The new "AI" versions are really bad at this, but even the ones available before the AI craze were still susceptible
- mh- 2y agoI'm far (far) from an expert in this field, but when you think about how audio is quantized into digital form, I'm really not sure how one solves this with the current approaches. That is: frequencies from one instrument will virtually always overlap with another one (including vocals), especially considering harmonics. Any kind of separation will require some pretty sophisticated "reconstruction" it seems to me, because the operation is inherently destructive. And then the problem becomes one of how faithful the "reproduction" is. This feels pretty similar to the inpainting/outpainting stuff being done in generative image editing (a la Photoshop) nowadays, but I don't think anywhere near the investment is being made in this field. Very interested to hear anyone with expertise weigh in!
