Post subject: | Stereo Tool 9.36 BETA |
Latest version - Beta 011 (Oct 26 2019) The BIMP Virtual Console The BIMP now comes with a virtual console, in which you can control the insertion level of all (for now at most 2) microphone inputs after processing. This replaces part of your hardware mixing console! With this it's now possible to have microphone processing, mixing and final processing with only 6 ms latency in total (for headphone output)! (For now it's only built-in, we will make a web interface to run on a tablet later) MicroMPX V3 We recently discovered that in MicroMPX V1 and V2, when audio started after a period of pure silence, a crackling sound could be audible. This was caused by a bug. (It only happened sometimes, and only after a period of pure silence, which is why nobody seems to have discovered this earlier). The new encoders can encode versions 1, 2 and 3, and the new decoders can decode all versions. If you update, update the decoders before you set the encoder to encode V3 - the old decoders cannot decode V3. If you are using an Omnia MPX Node or Omnia.9 with the latest software version, they both only encode V3, so you need a new decoder. Downloads

st-1770.pngIs this it on the primary processing page? Am I supposed to be seeing number values? It also appears to make audio stutter. |

That ITU1770 meter will get numbers, we're working on a new GUI that will be way more flexible. I've added this feature already but without the numbers so far... they will come. If you want to know what you're seeing: All the way to the right is 0 dB, every thick line is -6, so the display in the screenshot above indicates about -7 dB. It's normal that it doesn't go down when there's silence, that's how ITU1770 works. Very low level audio is ignored in the measurement. That's also what you want, if you're broadcasting a movie for example and there's a few minutes of (near)-silence you don't want to have to boost the rest of the audio to reach the correct target level. Glitches are probably caused by the CPU usage, I'll try to optimize it (that's why it's turned off by default). One way to optimize it would be to update the displayed level less often. |

Ah, ok, then every other loudness meter is wrong.

From https://www.itu.int/dms_pubrec/itu-r/re ... !PDF-E.pdf : Quote: The algorithm consists of four stages
– “K” frequency weighting; – mean square calculation for each channel; – channel-weighted summation (surround channels have larger weights, and the LFE channel is excluded); – gating of 400 ms blocks (overlapping by 75%), where two thresholds are used: – the first at −70 LKFS; – the second at −10 dB relative to the level measured after application of the first threshold. |

Thanks, that helps.... Glitches are probably caused by the CPU usage, I'll try to optimize it (that's why it's turned off by default). One way to optimize it would be to update the displayed level less often. A little more info: Not sure what all affects the update rate, but I'm using 150% quality on 3 hyperthreaded cores, at a 144hz refresh rate. |

Edit: Reduced update speed to once per second (which is fast enough), doing parts of the calculation on the fly so we don't have to examine everything anymore, at high sample rates (> 48 kHz) reducing it by skipping samples before sending it to the (heavy) resampler. Result: Values are still the same but the effect is almost invisible in the CPU load, even in debug mode With 192 kHz input, Old release CPU load with measurement disabled: 0.1% Old release CPU load with measurement enabled: 4.2% New debug CPU load with measurement disabled: 1.5% New debug CPU load with measurement enabled: 2.2% |
