Any blog posts on how this is working?

Seems to just be a beat matcher / BPM adjuster, which is interesting in itself, but quite basic features in any DAW/DJing software.
Wow, it actually produced something kind of reasonable for the least reasonable input I could come up with. I present "In the Hall of the Dracula Mountain King" https://rave.dj/1jK2s4-jAt3meg
Seems to be pretty awesome. I tested out two instrumental bits in Hardwell - Spaceman and SHM - Greyhound and found that the algorithm had some issues with the low end clashing on mixing between the songs https://rave.dj/qP-eYlelx75GjQ Though it leveled out after a few seconds. Would love to know more about how it works!
Definitely. I'm so curious.
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 all the complexity.

Even though I don't know how they'll monetize this, it seems a really well thought out product.

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

Thanks, that was very enjoyable and I think it would fit right in a world-class DJ mix.
I tried to give it a challenge, mixing two completely different genres of music – medieval with rap. Amazingly the medieval tune followed the beat of the rap song.

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

Depending on how you define product, this is a major show stopper. I'd say a product can't be called well thought out, if it doesn't have monetization thought out from the start. Although there is always advertizing, I guess..

But very nice tool/toy nonetheless!

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'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.

I agree, but two major issues here:

- licensing will be difficult without a paywall, I'm pretty sure this site is "illegal"

- there is no way to keep tweaking manually to correct bad sounding parts etc, which limits usefulness

As it happens I work on a similar iphone app called Pacemaker, which solves both of these problems (using spotify login and a bunch of edit tools, respectively)

Pretty interesting. I used to be heavily into the mashup scene, even going so far as to make mashup.fm (another turntable/plug.dj clone). Here's some of my favorite classical mashups alongside the rave.dj version:

Thomas the Tank Engine vs Biggie Smalls

Original: https://www.youtube.com/watch?v=ETfiUYij5UE

Rave.dj: https://rave.dj/XUBqv8IsZPVZMQ

This was the easiest as it's just a vocal track laid onto a beat, but it really jumps the tracks around a ton, seemingly randomly. It at least doesn't jump mid-measure though and fits with the beat.

------------------------------------

Modest Mouth (Modest Mouse vs Smashmouth)

Original: https://www.youtube.com/watch?v=wEmJH7JsKgM

Rave.dj: https://rave.dj/gUb_lU_PrHBdKA

The Neil C original is a classic, and really fits two songs together that don't belong near each other. Rave plays the intros in sequential order, with vocals overlapping all over. They really need a central channel filter to see if they can pop the vocals out from the instrumentals. This is really a tuesday-surprise lunchroom casserole of a mashup, with a rather abrupt ending.

------------------------------------

Korn vs Taylor Swift

Original: https://soundcloud.com/user-490703809/we-are-coming-undone-k...

Rave.dj: https://rave.dj/usdGtcmoNJeItg

This one really works because of some of the more complex editing on Isosine's part. The rave one is a disaster. Feels like you're standing in between two parties that are blasting two jams, that just happened to have their drops/choruses line up.

------------------------------------

Kanye West vs The Beatles

Original: http://mashup.fm/media/Hey_Jude_We_Major_More_Popular_than_J...

Rave.dj: https://rave.dj/ZcRpPLK6QZEvZA

This is a personal favorite, and I think it works because of how long the Hey Jude intro is. It really means you forget about Kanye completely until he jumps in. It works because of how slow of a buildup Hey Jude is. The Rave version has no nuance here. They speed up Hey Jude, up-pitching it in the process and making it sound like Raffi or some other child entertainer. They down pitch Kanye, making him seem like some gangsta thug. It really doesn't work at all.

------------------------------------

I really want this to become better, but I feel like it needs to be trained more tricks (vocal separation for one) to really be worth it. Also minor QOL improvement would be to allow you to preview tracks before you add them to the mix. Hard to find one that's a good audio only rip of a song sometimes.

Ok. I think I nailed the perfect one: https://rave.dj/ySGzN-0svLlPpA
definitely. bravo.
Wow, I have to say I'm kind of amazed this mashup was generated and not hand-crafted..
Really.. it sounds like someone just hit play on two songs at the same time to me. Beatmatching is trivial.
I guess the audio mix is good... The video was using 90% of my processing power, what in the world was going on there?
This one sounds pretty good wow. But Space Jam is hard to mess up to be fair.
Tried to use some generic pop songs ( https://rave.dj/BtHuRn1-lAnDEQ - [madonna - hung up] & [ timbaland - the way i are ]) and result is not bad at all, a bit cacophonous in some parts, but other than that it's [the smashup] quite good!

Awesome project! I just made https://rave.dj/0GU6N96tgPXj9Q and it's awesome! love being able to use a Spotify playlist.

Have you considered using BunnyCDN instead of Stackpath for the CDN? It'll probably be much cheaper.

Doesn't work for me - I get short glitchy bursts of noise and then it stops.

Can you hop onto the discord server so we can help you.
Actually that was caused by a rogue FB tab eating 100% CPU. [Sigh...]

All fine now.

As long as there's a pretty predictable 4/4 beat, it seems to do well.

DJ AssultPink - Ass ' n ' TT

Although the BPM detection usually works, It seems to have trouble getting the songs synced in phrase - 2nd tracks come in starting on the 3rd bar or something.

That blur filter absolutely annihilates my macbook's CPU.

EDIT: 4 hours remaining... hmmm.. feeding it a 400 track playlist probably wasn't a good idea
