how to slow songs down on mm2 radio

Quick answer

You cannot directly slow songs down inside MM2’s built‑in radio in Roblox. The radio only plays songs at their original speed using the song code; there is no built‑in “slow down” slider or tempo control for that feature.

If you want slower versions of MM2 radio songs, you must prepare them outside the game and then play them through your own device/music player while in MM2.

Why MM2 radio can’t slow songs

The Murder Mystery 2 (MM2) radio system is designed as a simple song code player :

  • You enter a code (e.g., from an MM2 song codes list).
  • The game fetches and plays the matching track from its internal library.
  • The playback is fixed at the original tempo and pitch; there are no in-game options to change speed, BPM, or tempo.

This is consistent with how most Roblox games handle music: they don’t include audio editing tools like tempo sliders inside the game client itself.

How to get slower versions of MM2 radio songs

Option 1: Use an online tempo changer

If you have the MP3/WAV file of a song that’s also on MM2 radio, you can slow it down using free online tools:

  1. Find or download the song file (from a legal source you own).
  2. Go to a tempo changer site like: 
 * [Soundtools Tempo Changer](https://soundtools.io/tempo-changer/)

 * [Audiotrimmer Audio Speed Changer](https://audiotrimmer.com/audio-speed-changer/)
  1. Upload the file.
  2. Use the slider to set a slower tempo (e.g., −20%, −30%).
  3. Download the slowed-down version.

These tools let you change speed without affecting pitch , which is ideal if you just want it slower for practice or listening.

Option 2: Use desktop software

If you prefer more control:

  • GarageBand (Mac)
    • Import the song.
    • Turn on Flex.
    • Change the BPM/tempo to a lower value.
    • Export the slowed version.
  • AudioRetoucher / tuneLite (Windows)
    • Open the audio file.
    • Use the “Tempo” slider (not “Speed”) to slow down without pitch shift.
* Save the new file.

These programs allow fine adjustments (0.1% steps) and support many formats like MP3, FLAC, M4A.

Option 3: Play the slowed song alongside MM2

Once you’ve created slower versions:

  1. Put them in a music player (e.g., Spotify local files, Windows Media Player, VLC).
  2. Launch Roblox and enter MM2.
  3. Play your slowed-down music on your device while in the game.
    • You can mute the in-game radio or ignore it.
    • Some players use headphones for game audio and another set for their slowed music.

This is the only realistic way to “slow songs down on MM2 radio” in practice: you’re not changing the radio itself, you’re replacing its audio with your own slower version.

Practical tips

  • Pick songs you already own legally; don’t try to extract audio directly from Roblox unless you have permission.
  • For practice or learning instruments , slowing to 60–80% tempo is common.
  • If you only want a chill vibe, a small slowdown (10–20%) often sounds natural without warbling.
  • Use lossless formats (WAV/FLAC) when possible to avoid quality loss when slowing down.

TL;DR

  • MM2 radio has no built-in slow-down feature.
  • To get slower versions of MM2 radio songs, you must:
    • Get the song file.
    • Slow it down with an online tool or desktop software.
    • Play that slowed version outside the game while you’re in MM2.
