Why check beats on a phone

808s and sub bass are where beats fall apart on small speakers. A phone speaker rolls off well above the fundamental of most 808s, so if the bass has no upper harmonics, it disappears. Checking on the phone while the pattern loops tells you right away whether the low end still reads, and you can fix it with saturation or a layer before you ever export.

Set it up in FL Studio

1. 01

   Install and scan

   Run the free MixOutpost installer and choose the Audio Unit (and the VST3 if you like). Run FL Studio's plugin scan so MixOutpost shows up in the plugin database.

2. 02

   Put it on the Master mixer track

   Select the Master track in the Mixer and load MixOutpost into the last effect slot, below your limiter or clipper. FL processes slots top to bottom, so the last slot hears the finished signal.

3. 03

   Start Sharing and pair

   Open the plugin, press Start Sharing, and scan the QR code with the MixOutpost app or the iPhone Camera. One pairing covers every instance on the Mac.

4. 04

   Play the pattern, tap Listen

   Hit play. The beat comes through on the phone, and keeps playing with the screen locked or while you're in another app.

Tips for FL Studio users

• Master insert, last slot: keep MixOutpost below everything else on the Master so the phone hears your final limiter.
• Hear the 808 alone: route your 808 to its own mixer track and add a second instance there. It shows up as its own source on the phone, so you can check it on the speaker by itself, or compare it with the full beat, with click-free switching and a volume per source for matching levels.
• Mono check for wide leads: stereo wideners on leads and pads can cancel in mono. Tap Mono on the phone to hear what a mono speaker does. See mono compatibility.
• Try the phone EQ: the diagnostic EQ lets you exaggerate the small-speaker roll-off without touching your mix, and it never affects the meters.
• Sample rate: FL projects often run at 44.1 kHz. The phone gets a high-quality conversion to 48 kHz; set the project to 48 kHz if you want the stream bit-exact.

What you can check from the phone

Beyond the low end, the phone's loudness screen shows integrated LUFS and true peak. If you're uploading to YouTube or Spotify, it shows how much the service would turn your beat down. With normalization on, a beat slammed to −6 LUFS won't play louder than one at −10; it just gets turned down further. Need to send a quick demo? Record it on the phone as a WAV and share it from there.
