And a surprisingly successful merger of Cutty Ranks and Abba with the awesome title of "Limb Queen" https://rave.dj/Mgv2ZGiuYfNnow I giggled all the way through it. A bit of better volume balancing where the two songs overlap and I'd play that at a party with no regrets...

nice - as you say, would be better if the Abba track was lower in the mix when it first comes in, but the timing and parts used to bring it in are spot on.

Perhaps the algorithm would do better with better quality versions of the track rather than youtube quality?

Hey all! I'm one of the devs at Rave (working on the website). This is really cool to see all this interest in us!

To address a few points I've seen on here: We do more than just beatmatching. That said, most of our recent technical advancements are done on our mix AI, as it's been our recent push. Give mixes a try (which work better the more songs you give them)! We'll be pivoting back to mashups soon as well to continue improvements on that AI, particularly rolling in some of the improvements we developed through the mix AI.

Our goals have really been to bring mashups and mixes to those who don't have the technical ability first and foremost, and focus on making it as accessible as possible. We want to make sure our baseline is solid before targeting customizations. I feel paraschopra's post really captured what we wanted to achieve.

Ultimately, we're still at the beginning of what we want to do, and have plenty of improvements on the way.

A few Raves I did that I like (most are with It's Everyday Bro because rave.dj tends to work well with that song): https://rave.dj/kzPLdIZQmIsS0Q https://rave.dj/y1qMUYY7GbNmKA https://rave.dj/JaJYoO_hBQNkjw https://rave.dj/U4BPJ9duII-o9Q (gets off-sync later sadly) https://rave.dj/Xx-6ojmH86hxpA None of these are perfect but Rave is A LOT of fun to mess around with, there's no denying that.

I think you'd probably like making a mix too! https://www.rave.dj/iOfKQXFw3TxTWA Just provide ~50 or more songs for best results

I've done it before, those are a lot of fun too.

We're aiming to make the process as simple as possible, so anyone can make mashups/mixes, and will add on customizations over time. Our focus first and foremost will be to make sure that the core process is solid before we add on to it.

Our AI does do more than beatmatching as well. Though a lot of that is going to be more evident in our mix AI, which we've been focusing on recently.

Agreed! I'm in a band called The Wonder Bars[1], and we play house music live with real instruments, but we also include drum machines. We're very far from computers being able to improvise (well), and 4-5 humans playing live instruments is just a crowd-captivating visual. Along with Agent Zero[2], Worldtown Soundsystem[3], and several other bands in the Philadelphia area, we make up a vibrant "live electronic" scene…

Oh I definitely agree we have nothing to worry about :) I may have to check you out though! I enjoy live house of many flavors. But at the same time, photo style transfer is...impressive[1]. It's interesting to me that so many engineers are focused on creating machinery that learns the photographic signal subspace, but there's not too many working on the audio signal subspace.

If there is someone here who also played Donkey Kong Country 2 in his/her childhood: Some of its tunes make for a pretty decent hip hop beat.

All it takes is a pivot at that point. There are currently 3 major DJ software products - Serato, Rekordbox and Traktor - the ability to quickly throw together a few different tracks into a mashup could be a nice killer feature for one of them to acquire. Or, playout software for a bar - queue up a load of music of a similar genre and have an automix created.

> There are currently 3 major DJ software products - Serato, Rekordbox and Traktor There's also MIXXX which is open source: https://www.mixxx.org/

Indeed - but if you want to be acqui-hired you go for one of the commercial offerings.

As an aside, Mixxx is an awesome piece of software, it's not quite as slick as Serato et al, but it works fantastically if your controller is suitably mapped, and is timecode vinyl agnostic which is a nice plus.

Some feedback:

* Awesome job, here are some feature suggestions:

* The ability to rate the mix/mashup as the author

* The ability to rate as an audience

* visual of the algo's understanding of the songs sound profile and how its lining them up

* The ability to select the time-range of the song which must be included/excluded from the mix

* ability to ask it to weight a repeating frequency of a song

* name of the artist/track/video playing displayed

Where are you guys located?

This is how well thought out products look like. - Really simple and intuitive start. I created my first mashup within first 2 minutes and at all times knew exactly what I was doing - Inbuilt virality. People will show off their produced mixes to their friends and on social media. - Actually solves a pain point. How many of us have tried mixing songs and gave up? This gives a sense of creativity while taking care of…

Not only that, but the small things like mashing up the song title and album art truly make this a quality product. Here is my first try: Disclosure - Bang That + The XX - On Hold = Hold That https://rave.dj/1F1p4ZS9ipWmYA

This is definitely the best one in this thread so far.

To be honest I didn't think my comment would get that much attention - and if I did I would've worded it a bit more gently. I think the framework that you've built around this product is really, really, really impressive (the virality and interactivity, for example). But I also think it's a very hard problem that you've set out to tackle. I alluded to it a bit elsewhere in this thread, but there hasn't been nearly as much work put into audio signal learning as there has been photographic signal learning. I'm really excited to see what else can be done, and I'm happy to see that someone is trying to do it. I wish you the best of luck

(But I'm also hoping that this doesn't further dilute the music industry by making music "production" even easier. Pop music is already "algorithmically solved", and other genres aren't as unique as any fan would like to think.)
