Stop switching apps to check your SPL.
A calibrated SPL meter that runs as a VST3 plugin inside your DAW or VST host, or as a standalone app.
Measure dBA, dBC, peak, and 15 min of history.
Buy once, own it forever. No subscription. Mac or Windows.
Why a plugin?
Every other SPL meter is a separate app running off to the side. dBB SPL Meter drops onto a track or rack, right where you're already working. Route your measurement mic, calibrate, and you're reading the room.
Live multitrack recording
Insert it as an input FX on your measurement mic and watch SPL right beside the mix you're recording.
Live VST host
Running SuperRack Performer, Yamaha VST Rack, or LiveProfessor? Drop it on an empty rack and read your room.
Standalone when you want it
No DAW needed. Same meter, same calibration, same reports, on a dedicated laptop or in the control room.
Your whole mix lives in one place. Now your SPL does too.
Measurement you can trust
A phone app guesses with a mic built for voice calls. dBB SPL Meter calibrates to your measurement mic and your gear, so the number you're reading is the real level in the room, the kind you can put in a report or make a call on.
Calibrate to your mic
Load your mic's calibration file and dBB SPL Meter will apply a linear-phase FIR filter that keeps peak timing intact. Reference accuracy, not a guess.
Works with your rig
Any interface the OS sees, at any sample rate from 44.1 to 192 kHz. Works with Dante Virtual Soundcard, MADI, RME, MOTU, Behringer WING and X-LIVE.
Measure many at once
Insert multiple instances in one session to monitor several microphones independently, FOH, balcony, and the stage at the same time.
A real standard
Validated against IEC 61672-1 Class 1, and ANSI S1.4 Type 1, the spec professional sound level meters are measured against.
Plus true peak detection with 4x oversampling, A and C weighting, and Fast, Slow, and Leq timing per IEC 61672-1.
Documentation that holds up
When someone asks how loud it was, the answer is already logged.
dBB SPL Meter logs metering the whole session and can export in two ways: a clean PDF with your logo for a quick volume summary, and a full CSV with every data point. Both are timestamped and verifiable, so the numbers hold up after the room clears. Forget to start the logging? dBB SPL Meter automatically keeps a running meter log in the background for exporting your session, up to 24 hours of history.
Built for the people running the room
- Live sound engineers watching levels song to song
- Touring engineers keeping FOH and stage in venue compliance
- Production managers and corporate AV documenting levels and keeping shows consistent
- Broadcast and studio engineers monitoring SPL in the control room
- Church and worship tech teams tracking service levels and reporting to leadership

FAQs
How is this different from free SPL apps?
Phone apps use an uncalibrated phone mic and give you no documentation or DAW integration. dBB SPL Meter runs in your DAW, VST Host, or as a standalone program; uses your real measurement mic through your interface, accepts microphone calibration files ensuring high accuracy of metering. dBB SPL Meter also exports reports you can hand to a venue, client, or insurer.
How is it different from other SPL software?
Almost all SPL software is standalone-only. dBB SPL Meter is one of the only calibrated SPL meters that runs as a VST3 plugin, on any track or rack, with as many instances as you need. It runs as standalone software too.
Why a VST3 plugin?
Computer processing and screen space is always at a premium. By using dBB SPL Meter as a VST3 plugin, you are sharing the audio processing of your DAW or VST Host rather than adding another separate audio processing thread. dBB SPL Meter can run alongside your live plugins in hosts like Waves SuperRack Performer, LiveProfessor, Yamaha VST Rack, VST Host and more. Or use it in your DAW while you are multi-track recording your audio in hosts like Pro Tools, Reaper, Studio One, Logic and more.
Do I need a measurement microphone or SPL calibrator?
You'll get the most accurate readings with a proper omnidirectional measurement microphone, some people call them an RTA Mic. The SPL Calibrator makes your metering even more accurate and is the fastest way to calibrate your readings. Without a calibrator you can temporarily push a 1 kHz tone through your sound system and take a reading with a handheld SPL meter in dBA Slow. Enter the level into dBB SPL Meter and you can track relative levels with good accuracy.
How accurate is dBB SPL Meter?
dBB SPL Meter was developed and tested to be accurate with current sound level meter standards. The intent was to have a highly accurate meter readout that could pair with an accurate audio interface and measurement microphone.In the most basic sense, a sound level meter's accuracy for measuring decibel levels comes down to how accurately the meter measures and compares the audio source through A-weighting and C-weighting filters, which dBA and dBC are calculated from.
These filters are accurately defined as worldwide industry standards in IEC 61672-1, ANSI/ASA S1.4-2014 / Part 1, and ANSI S1.4-1983. dBB SPL Meter conforms to the Class 1 and Type 1 tolerance limits (which are the highest accuracy standards) set by those industry standards. This means that paired with a calibrated microphone, audio interface, and SPL calibrator, dBB SPL Meter can be trusted.
Does it work with Dante or MADI?
Yes, plus MOTU, RME, and any interface the OS recognizes. As long as your computer accepts audio from your interface, dBB SPL Meter can use that audio either in the standalone software or as a plugin in your VST host or DAW.As a plugin it reads whatever channel you insert it on.
Can I run multiple instances?
Yes, on any computer dBB SPL Meter is activated on, you can run multiple instances, each measuring independently.
Can I move it between computers?
Yes. Self-service deactivation frees a slot to move machines or platforms. Activation & deactivation requires an internet connection for license verification. After dBB SPL Meter is activated it does not require the internet to function.
Does dBB SPL Meter track or share usage analytics?
dBB SPL Meter does not track usage analytics, collect data, record audio, or share metrics. The plugin validates your license using cryptographic signatures stored on your machine and works fully offline after activation. dBB SPL Meter only uses the incoming audio for SPL measurement and logging for your purposes.
Does my license work on both Mac and Windows?
Yes. One single license activates on both platforms - up to two devices total. Use it on your Mac at home and your Windows machine at the studio, for example.
