Nothing to A/B. MS Field measures, it doesn't process.
On the panel
- SpectrumMid and side on one graph, from the same frame as every readout on the panel.
- GoniometerDraws the stereo field. A vertical line is mono, and the further it spreads sideways, the more side signal there is.
- CorrelationThree bands, each with its correlation and the level a mono fold would cost.
- Bass CheckTen third-octave bands from 25 to 200 Hz. It names the worst one and suggests a crossover.
Every graph and number comes from the same 2048-sample frame, so a wide-looking curve can't sit next to a reading that says otherwise. Bass Check uses a frame four times longer. It names the frequency below 200 Hz that loses most in mono, and how many decibels a fold would give back. It reads the input and leaves the audio alone.
Views
Full range
20 Hz to 20 kHz, updated every frame: the spectrum, the three-band correlation and mono-loss, width and balance.
Bass Check
Trades update speed for resolution below 200 Hz. Ten third-octave rows instead of three wide bands, plus the worst offender and a mono-below recommendation with the dB it recovers.
What it does
- Mid/side spectrum, correlation and mono-loss computed from one shared frame, so the three can never disagree with each other
- Three-band readout (low, mid, high) shows correlation and how much level a mono fold would cost, colour-coded from safe to a fold that will lose it
- Width reads side level against mid as a percentage: 0 is mono, 100 is equal energy either side
- Balance meter shows the image sitting left or right, in dB, from the same sums the correlation is built on
All 8 features
- Bass Check takes a frame four times longer to resolve ten third-octave bands from 25 to 200 Hz
- Names the worst bass band by frequency and how much it loses on a mono fold, and recommends a crossover with the dB it would recover
- The frame length adapts to the host's sample rate, so the low band keeps the same resolution at 44.1 kHz and at 96 kHz
- Analysis runs off the audio thread. It reads the input and changes nothing in the signal path
