dep#0002: You could have just redirected the welcome to a new channel yk JL#1976: Let's keep all the discussions in this general chat, so #🙏︱welcome channel serves as a landing page and rules page if we get more users. ZestyLemonade#1012: **Welcome to #💬︱general** This is the start of the #💬︱general channel. JL#1976: You learn something new every day 🙂 『ｋｏｍｏｒｅｂｉ』#3903: where's the language list for riffusion 『ｋｏｍｏｒｅｂｉ』#3903: i want to know what genres it supports 『ｋｏｍｏｒｅｂｉ』#3903: found it nvm db0798#7460: Where is it then? 『ｋｏｍｏｒｅｂｉ』#3903: https://huggingface.co/riffusion/riffusion-model-v1/blob/main/tokenizer/vocab.json 『ｋｏｍｏｒｅｂｉ』#3903: here db0798#7460: Thanks! 『ｋｏｍｏｒｅｂｉ』#3903: it has a lot of non-musical words though doesn't exactly help 『ｋｏｍｏｒｅｂｉ』#3903: not too sure how it's supposed to work

db0798#7460: This is identical with the vocab.json of the Stable Diffusion 1.5 base model https://huggingface.co/runwayml/stable-diffusion-v1-5/raw/main/tokenizer/vocab.json db0798#7460: I think the genre names probably come from somewhere else dep#0002: @seth (sorry if too many pings) I am trying to make my own audio seed. Could the spectogram_from_waveform (from https://github.com/hmartiro/riffusion-inference/blob/6c99dba1c81b2126a2042712ab0c35d0668bd83c/riffusion/audio.py#L89) be used to transform a WAV tensor's (I'm guessing from torchaudio.load) into a spectogram object, and then do the reverse of spectrogram_from_image to basically have a custom seed? dep#0002: I also see the following comment: ``` """ Compute a spectrogram magnitude array from a spectrogram image. TODO(hayk): Add image_from_spectrogram and call this out as the reverse. """ ``` I could try doing it alfredw#2036: Can we make it 10x better soon? dep#0002: I was looking into converting it to TensorRT with Volta but it seems it has 1 more layer 『ｋｏｍｏｒｅｂｉ』#3903: could we send some songs of different genres so that the ai can generate a wider array of genres? i have a decent amount of obscure genres in my playlist

alfredw#2036: what's the training set? 『ｋｏｍｏｒｅｂｉ』#3903: vaporwave, chopped and screwed, free folk, experimental rock, art pop, etc? 『ｋｏｍｏｒｅｂｉ』#3903: don't think the ai knows those genres too well dep#0002: gptchat: ```python def image_from_spectrogram(spectrogram: np.ndarray, max_volume: float = 50, power_for_image: float = 0.25) -> Image.Image: """ Compute a spectrogram image from a spectrogram magnitude array. """ # Reverse the power curve data = np.power(spectrogram, power_for_image) # Rescale to the range 0-255 data = data * 255 / max_volume

# Invert data = 255 - data # Flip Y and add a single channel data = data[::-1, :, None] # Convert to an image return Image.fromarray(data.astype(np.uint8)) ``` dep#0002: anyways I will see what I can do dep#0002: this is basically audio2audio 『ｋｏｍｏｒｅｂｉ』#3903: could we help increase the dataset dep#0002: If they release the training code I will train it on the entirety of pandemic sound db0798#7460: I would also like to have some way of adding things to the dataset 『ｋｏｍｏｒｅｂｉ』#3903: i'd train it on my playlist + more albums that i somewhat like

Slynk#7009: omg I've been dying for something audio related to happen with all this AI hype. 『ｋｏｍｏｒｅｂｉ』#3903: so that way the ai can endlessly churn out music i like >:D my playlist would probably be too smoll for it though Thistle Cat#9883: Hi what's happened? Paulinux#8579: What I'm doing wrongly? I have URL like this: https://www.riffusion.com/?%20&prompt=folk&%20denoising=0.05&%20seedImageId=agile And sometimes this AI couldn't produce for me anything db0798#7460: Try the Colab (https://colab.research.google.com/drive/1FhH3HlN8Ps_Pr9OR6Qcfbfz7utDvICl0?usp=sharing) instead, perhaps? Colab seems to work consistently Paulinux#8579: OK, thanks 『ｋｏｍｏｒｅｂｉ』#3903: ooh wait i know what i'd do i gather all the alternative/avant-garde genres i can muster, select some albums from those genres (with the genre names + other descriptions with them) and then i'd put those in the ai dep#0002: overloaded dep#0002: If anyone wants I can host a mirror hayk#0058: We have this code and it's very simple, we just haven't added it to the inference repo dep#0002: Could it be possible for you to send it here or push it to the repo?

hayk#0058: Yeah if you open an issue on github we will aim to get to it soon! AmbientArtstyles#1406: Hey @ZestyLemonade, I'm writing an article about sound design (sfx for games/movies) and Riffusion, can I use your sentience.wav clip in it? AmbientArtstyles#1406: I so want to collaborate on training the algorithm with my personal sound libraries. 🎚️ 🎶 Thistle Cat#9883: Has the website been fixed? JL#1976: Works for me. Thistle Cat#9883: Nice! Thistle Cat#9883: I will have to check it again tonight Tekh#3634: How do I make a continuous stream of interconnected clips with the colab? Tekh#3634: also, is there any way to change tempo and such like on the webapp using the colab? dep#0002: thanks pls do so asap I cant wait dep#0002: in the meantime im getting things like these dep#0002: https://cdn.discordapp.com/attachments/1053081177772261386/1053101779992186941/FINAL.png Thistle Cat#9883: Anyone hearing a snapping noise when it goes to the next spectrogram? yokento#6970: Can you seed riffusion with your own clip of audio? April#5244: 14gb ckpt?

dep#0002: thats what I was trying Jack Julian#8888: Crazy stuff yall im a musician myself, and seeing this is both interesting and 'worrying'. Love how you thought this out and put it to works. April#5244: was hoping to gen using automatic1111's sd webui and perhaps finetune the model using dreambooth. but I feel like I'm in a bit over my head lol WereSloth#0312: you'll need to convert music to a spectrogram WereSloth#0312: and then, yes, you should be able to dreambooth db0798#7460: Is there a script for converting your own audio sample to the right kind of spectrogram already available anywhere? There seem to be functions that do this in the Riffusion codebase but I guess they don't work as a standalone script? dep#0002: the image_from_spectogram function is missing dep#0002: https://github.com/hmartiro/riffusion-inference/issues/9 dep#0002: supposedly they have it but they haven't added it yet dep#0002: Maybe tomorrow it could be ready lxe#0001: 👋 lxe#0001: Just wanted to stop by and say how awesome this thing is lxe#0001: Wonder if something like deforum for it is in the works. justinethanmathews#7521: this is very interesting. i am mostly in the "afraid of AI" camp, but music is a field I understand and I can see how interesting this is.

this might be a stupid question. but what was this trained on? April#5244: I'm also curious about the dataset tbh April#5244: also managed a small success: converting from wav file to spectrogram and back is working perfectly, and I have a working ckpt that can generate the spectrogram images. Next is to make a finetuning dataset and run it through dreambooth 🙂 dep#0002: Can you share your convertor? April#5244: https://pastebin.com/raw/0ALzwee4 April#5244: just a word of warning @dep I have no idea what I'm doing and this code was generated with the help of an ai and my own tinkering. might have some serious stuff wrong with it lol April#5244: I've only tested it on the generated 5-second wav files that are created from the sister script April#5244: also trying to re-input the generated pics doesn't work right so I have to manually save in paint and then it works for some reason lol April#5244: but from my testing it seems to work well enough April#5244: currently seeing if I can get it to work from mp3 and clip like the first 5 seconds or something dep#0002: time to train on the internet dep#0002: 🥂 April#5244: okay so I think I got it working with mp3 so I threw a whole dang song in there and it generated an image but it's much wider in resolution, and cropping it down just results in junk lol April#5244: might have to limit it to 5 seconds

April#5244: ``` def spectrogram_image_from_mp3(mp3_bytes: io.BytesIO, max_volume: float = 50, power_for_image: float = 0.25) -> Image.Image: """ Generate a spectrogram image from an MP3 file.

April#5244: "clip.wav" is the 5 second clip from the original mp3 that's used for conversion. the image is the converted spectrum from the mp3. and output.wav is the reconverted song from the image April#5244: scripts used https://cdn.discordapp.com/attachments/1053081177772261386/1053176008141963364/audio2spectro.py,https://cdn.discordapp.com/attachments/1053081177772261386/1053176008590770236/audio.py April#5244: notably the script doesn't clip the first 5 seconds, but rather the next 5 after that April#5244: since I wanted to avoid the sometimes slow intro that songs have lol April#5244: still need to do some more work on the scripts before I can have it auto-generate some dataset images properly @.@ April#5244: might actually need to fetch later in the songs lol 🤔 April#5244: I noticed it still distorts the sound a bit... April#5244: comparing: clip is the cropped audio, output.wav is the audio->img->audio convert https://cdn.discordapp.com/attachments/1053081177772261386/1053177485497475113/output.wav,https://cdn.discordapp.com/attachments/1053081177772261386/1053177485862387712/clip.wav dep#0002: WoohH!!!!! dep#0002: I dont know how to thank you dep#0002: and its just been a day Lol dep#0002: @JL may I suggest some emojis April#5244: I'm sure someone smarter than me can figure out how to fix it lol JL#1976: Yes, let me know if you have any cool ideas for the channel dep#0002: Can I dm you the stickers and emojis

dep#0002: I prob will also make it into a bot dep#0002: (riffusion) dep#0002: although I've also heard that another dev is also working on one dep#0002: u know lopho from sail? dep#0002: the decentralized training server dep#0002: I might ask him tomorrow dep#0002: he knows a lot about this stuff dep#0002: he rewrote the bucketing code himself lol dep#0002: yet haru didnt merged it and he deleted it JL#1976: Yup dep#0002: hm.... I dont think we should mess with the channels.... dep#0002: but its worth the attempt April#5244: 🤷‍♀️ honestly most of this code is ai generated. I don't know anything about music lol. removing that line of code seems to break the conversion entirely April#5244: looking into the actual conversion a bit more it seems like the sample rate is getting changed which may be why the quality is decreasing 🤔 dep#0002: = ( https://cdn.discordapp.com/attachments/1053081177772261386/1053183348715032576/recompiled.mp3

dep#0002: maybe the first finetune April#5244: I wonder if there's a way to just have the whole song in the image 🤔 April#5244: I guess it'd have to be a larger image... vai#0872: any way to fine tune this model? Milano#2460: hi All! are you aware of https://www.isik.dev/posts/Technoset.html ? Milano#2460: Technoset is a data-set of 90,933 electronic music loops, totalling around 50 hours. Each loop has a length of 1.827-seconds and is at 128bpm. The loops are from 10,000 separate electronic music tracks. Milano#2460: I'm wondering how best to preprocess it. db0798#7460: I think this one is pretty cool actually, sounds like Autechre jacobresch#3699: here's an extension for auto1111 which automatically converts the images to audio again 🙂 https://github.com/enlyth/sd-webui-riffusion JL#1976: Pinned a message. HD#1311: this is exactly the kind of plugin I was looking for HD#1311: thanks HD#1311: I'll report if it works when I get home from work April#5244: Worked for me but it messed up my sd install and python because it tried to install pytorch audio which I already had

JeniaJitsev#1332: Great work, folks, very impressive! I am scientific lead and co-founder of LAION, datasets of which are used to train original image based stable diffusion. Very nice to see such a cool twist for getting spectrogram based training running. We would be very much interested to cooperate on that and scale it further up - just join our LAION discord : https://discord.gg/we4DaujH JL#1976: Welcome, happy to see you here!
