A Discord soundboard that won't get you muted

Discord has had a built-in soundboard since 2023, which means most of the elaborate bot-and-virtual-cable setups people still recommend are no longer necessary for the common case. They are still necessary for some cases. It is worth knowing which one you are in before you install anything.

The built-in soundboard

In any voice channel there is a soundboard button in the control tray. It plays short sounds to everyone in the channel, and any server member can use it unless permissions say otherwise.

To add your own sound to a server:

1. Download the clip as an MP3.
2. Open Server Settings → Soundboard. You need the Manage Expressions permission, so on someone else’s server you will have to ask.
3. Upload the file, give it a name, and optionally attach an emoji.

The constraints are tight and they are the reason people still reach for alternatives:

• Sounds must be very short — a few seconds at most.
• There is a hard file size limit, measured in hundreds of kilobytes.
• The number of soundboard slots a server gets scales with its boost level. An unboosted server gets few.
• The sound is attached to the server, not to you. It does not travel with your account.

For most people that is enough, and it is by far the least fragile option because nothing is intercepting your microphone.

When the built-in one is not enough

You need something else if you want a personal soundboard that works on every server, if your clips are longer than the limit, or if you want the audio to go into a stream as well as a voice channel.

The general approach is a virtual audio device: software creates a fake microphone, you route both your real mic and your soundboard output into it, and you select that fake microphone in Discord. Discord then hears one combined input and is none the wiser.

Turn off the processing

This is the step that actually determines whether your soundboard sounds good, and it is skipped constantly.

Discord’s voice settings include noise suppression, echo cancellation, and automatic gain control. All three exist to make a human voice in an untreated room intelligible. All three are actively hostile to a sound effect.

• Noise suppression is trained on speech. A game sound or a musical sting does not look like speech to it, so it gets treated as noise and gutted.
• Automatic gain control continuously adjusts your input level to keep your voice consistent. Play a loud effect and it clamps down, then spends the next second or two ramping your actual voice back up. This is why people sound muffled immediately after a soundboard hit.
• Echo cancellation can mistake your own soundboard output for echo and suppress it.

Turn all three off in Discord’s Voice & Video settings if you are running a soundboard through your mic input. You will need to deal with your room noise some other way, which is a real cost — but a soundboard fighting noise suppression sounds broken, not quiet.

The part about not getting muted

A soundboard is a shared resource in a way that a microphone is not. Some practical rules that keep them from being banned outright:

• Level your clips before you upload them. A sound that is twice as loud as everyone’s voice is not funnier, it is just louder, and it is genuinely painful in headphones.
• Be careful with the pranks category specifically. Sudden high-volume audio is not a joke to someone with hyperacusis, misophonia, or a hearing aid, and you cannot see who is on the other end.
• Do not play sounds over someone who is talking. This is the entire reason for most mutes.
• Assume any sound you add will be used by the most annoying person in the server at the worst possible moment, because it will be.

Server admins: the soundboard permission can be restricted per-role and per-channel. Doing that early is much easier than taking it away after it becomes a problem.
