MASHUP TUTORIAL

Step by step guide to mashups (with audacity)

1. Download two songs
Space Jam theme: Highest quality https://www.reddit.com/r/comeonandslam/comments/1y133y
John Cena's theme: Vocals only https://redd.it/3p0osq Normal https://youtu.be/wjNtB5g70ic
Songs with lyrics: Look here first https://www.reddit.com/r/IsolatedVocals (AND USE GOOGLE)
Anything else: Most useful thing http://www.youtube-mp3.org/

2. Beats per minute
Space Jam theme: 132
John Cena's theme: 87 or 174
Thomas the tank engine: 99.67
Undertale ost: List here https://redd.it/44erms
Using google: Might take more than 1 website to find the bpm
If all else fails: Use http://www.all8.com/tools/bpm and/or trial-and-error

3. Which bpm to change?
Space Jam: Always change Space Jam's bpm (overrides everything below)
Thomas the tank engine: Always change the other song's bpm
One song has vocals: Change the bpm of the vocals, especially with isolated vocals
Both/neither have vocals: Depends, but i recommend changing the slower bpm

4. Audacity

While it might be the literal worst program to use for mashups, it's cross platform, so fuck it

5. How to change the bpm
If you put both songs in audacity already, there should be two tracks, but if you didn't, put both songs into audacity so there's two tracks

With the track of the bpm to be changed, click the area between the track name and the Mute/Solo buttons to select the entire track, then in the Effect menu, choose Change Tempo... and fill in the Beats per minute fields, first one is the bpm of the track you selected, and the second is the bpm of the track you didn't select
After that, click ✔️OK

5. Lining them up
This one is a bit harder to explain but basically move the first beat of each song so they happen at the same time
With the zoom tool middle-click then left-click four times and make sure they still line up at that zoom level ok go make turret proud
