How to Set and Test Microphone Levels in BandLab

A good recording level in BandLab keeps your voice or instrument clearly above background noise without clipping. This guide covers choosing the input device, setting the level where it actually changes the recording, and confirming the result with a short test take.

Before you start

BandLab is an online service. You need an account and an internet connection, and you work in either a supported desktop browser or the BandLab mobile app. Audio is captured by your device, but projects are saved to your BandLab account rather than only to local storage. If privacy or file retention matters to you, check BandLab's current privacy policy and account settings instead of assuming how recordings are stored or shared.

• A microphone connected to your computer or phone and recognised by it: a USB mic, an audio interface, a headset or the built-in mic.
• Headphones selected as the output device, so playback does not leak back into the microphone.
• Microphone permission granted to your browser or the BandLab app.
• Other apps that may hold the microphone, such as video calls or voice recorders, closed.

Step-by-step instructions

The recorded level is set before the signal reaches BandLab. A track's volume fader changes how loud that track plays back, not how strong the recorded signal is, so adjust gain at the source first. Before changing anything, note your current gain-knob position or system slider setting so you can return to it.

1. Choose the input device

On a computer, make sure your microphone is the default input device in the operating system. If the browser asks for microphone access when you open the studio, allow it. If you blocked access earlier, re-enable it in the browser's site settings and reload the page. If your version of BandLab shows its own input selector, choose the same microphone there. On a phone, an external mic connected by cable or adapter usually replaces the built-in one. In either case, confirm in the phone's settings that the BandLab app has microphone permission.

2. Set the input level at the source

Use the gain control closest to the microphone:

• Audio interface or USB microphone with a gain knob: start low, then raise it while you speak or play at performance volume.
• Windows: open Settings, then System, then Sound. Select your input device and adjust its input volume.
• macOS: open System Settings, then Sound. Choose the microphone under Input and adjust the input volume slider.
• Phones: there is usually no system input slider. Control the level with mic distance and, on external mics, any gain control on the device.

Set the level using the loudest part you plan to record, not a quiet warm-up. Most singers and players get louder once a real take starts.

3. Arm a track and watch the meter

Create or open a project, add a voice or audio track, and arm it for recording. Speak or play while you watch the track's level meter. A common guideline is to keep peaks well below the top of the meter. If the meter has a scale, aim roughly for the -12 to -6 dBFS range to leave room for louder moments. If the meter hits the top or shows a clipping indicator, lower the source gain. If the meter only moves while recording, make a short test take instead.

4. Decide on monitoring

If your version offers input monitoring, turning it on lets you hear yourself through BandLab, with some delay from the browser and device. Keep headphones on while it is enabled to avoid feedback. If the delay is distracting, turn monitoring off and rely on the meter, or use direct monitoring on your audio interface if it has that feature. Monitoring volume does not affect the recorded level.

Check the output

Record a short test take at full performance volume, and include your loudest phrase or passage. Then check it:

• Look at the recorded waveform. It should be clearly visible, but its peaks should not look flattened at the top and bottom, which is a sign of clipping.
• Play the take on headphones. Listen for distortion on loud parts and for uneven volume.
• Listen to a pause. Background noise you hear there will rise further if you later add compression or boost the track.
• Compare the take with other tracks in the project. You can balance playback with the track fader afterwards.

Clipping that is recorded into the file cannot be removed by lowering the fader or adding effects. The reliable fix is to re-record at lower gain, so a slightly quiet take is safer than a clipped one. Export formats and quality depend on the options in your version of BandLab. Check them when you export rather than assuming a particular sample rate or bit depth.

Common problems and next steps

The meter does not move

First confirm that the microphone responds in the operating system's sound settings. Then check the browser or app permission, make sure the track is armed and set to the correct input, and close other apps that use the microphone. After you change permissions or plug in a device, reloading the page often helps the browser detect it.

The recording is too quiet

Raise the gain on the interface or the system input slider, or move closer to the mic. Dynamic microphones usually need more gain than condenser microphones, so a low-output mic may need the interface gain set fairly high.

Distortion or clipping

Lower the source gain, back away slightly from the mic or angle it away from loud sources, and record again. If you hear distortion while the meter looks safe, check for a faulty cable, an engaged or disengaged pad switch, or an overloaded preamp on the interface.

The level jumps around or sounds processed

Operating systems, headsets and browsers can apply automatic gain, noise suppression or echo cancellation designed for calls. These can make the level pump or thin out the sound. Turn off audio enhancements or voice processing in your system or device software where available, then test again.

Crackles, dropouts or odd pitch

These usually point to device or driver problems rather than level. Check that the interface's sample rate in your system audio settings is consistent with what your other audio apps use. Also try a different USB port and close heavy browser tabs. If the problem continues, test the same microphone in another app to tell whether the cause is BandLab or the hardware.

Too much background noise

Raising gain does not fix a noisy room. Move closer to the microphone so you can use less gain, switch off fans and other noise sources, and point a directional mic away from the noise. Noise reduction applied later works best on a clean, well-levelled take.
