Sonic with a DSi

Recording high-quality audio can be quite tricky, but it doesn’t have to be. Here’s a list of our favourite audio recording techniques.


Sock on Mic

This ancient technique still works excellent today and involves nothing but a sock and an audio source.


You will need:

  • One clean sock
  • A device capable of outputting audio
  • Your DSi, 2DS, or 3DS


Here’s how it works:

1. Grab your console and create a new Flipnote. Fill it with blank pages (depending on how long you want your Flipnote to be).Flipnote Studio Edit Screen


2. Head on over to the audio recording screen. Once there, place your sock over the microphone on your console.

💡 Tip: If you’re unsure where the microphone is on your console, take a look at this guide:Microphone locations on various Nintendo consoles


3. Grab your audio source and place it on the sock, right on top of where the microphone would be.A phone on a sock, which is on a 3DS.


4. Play your audio but don’t hit record yet. We need to test for audio clipping.

💡 What isaudio clipping”? Audio clipping is a form of distortion. If your audio source is too loud, the audio will distort. Adjust the volume of your audio source (if possible), so the waveform shown on the right of the sound recording screen is just below the red section.Audio recording screen on Flipnote Studio


5. Once you’re happy, hit record and that’s it!


Speed 5 to 6

Here’s another excellent method for capturing high-quality audio. You can even combine this with the above technique to achieve incredible sound quality!


You will need:

  • .mp3 file of the audio you want to use
  • Audio editing software (we recommend Audacity)
  • Your DSi, 2DS, or 3DS


Here’s how it works:

1. Acquire a .mp3 file of the audio you wish to record and import it into your audio editing software.A web browser downloading an audio file


2. Slow down the audio to 50% speed and save it as a new file. In Audacity, you can achieve this by navigating to Effect > Change Speed.Audacity's Change Speed screen


3. Use the Sock on Mic technique outlined above, but make sure you record the slowed-down audio at Speed 5.Speed 5 on Flipnote Studio


4. Once you’ve finished recording, change your Flipnote’s speed to Speed 6, and hit play!


TRRS Splitter (Requires a 2DS or 3DS Console)

WARNING: This setup is experimental and may not work for you. We’re sharing our configuration and what works for us.

Get ready; you’re about to be blown away with this technique. You can even combine it with the Speed 5 to 6 method for superior sound quality.


You will need:

  • CTIA compliant TRRS Splitter
  • A PC or Laptop
  • A 2DS or 3DS system (this will not work on a DSi system)


Here’s how it works:

1. Find a TRRS splitter that is CTIA compliant (not OMTP). We use the Rockit Audio Splitter (affiliate link), and it works great.

2. Start by plugging the splitter into your console.

3. Now, plug in a regular TRS AUX cable into the microphone port.

4. Finally, connect the other end of the TRS AUX cable into your PC or laptop. So far, we have not been able to get this to work using a phone.



5. On your computer, play some audio and see if your console picks it up. If successful, you’ll see the waveform moving to the music. If not, check your connections, try a different TRS AUX cable, or try a different TRRS splitter.

💡 What’s going on here?
We’ve tricked our console into thinking our computer is a microphone. The console will receive anything (audio-wise) we output from the computer.


6. Adjust the volume on your computer, so the audio doesn’t clip. On our system, somewhere between 4 and 6 works best; your mileage may vary, however.Audio Mixer


7. Use the Speed 5 to 6 technique outlined above and hit record. Make sure the slowed-down audio is playing from your computer and is being picked up by your console.Speed 5 on Flipnote Studio


8. Once recorded, unplug the cable from your console and set the Flipnote’s speed to Speed 6, and that’s it!
