Hans, I think you should meet in the middle. You ask a 1000 Euro

Yeah, those are the folks that think that 1024x768 makes things "too small", so they bump up the font size to compensate, not realizing that if they'd give it more time, their eyes will adjust. That said, you might have a few accessibility people here and there. I guess you have to try to gauge the audience. Were those that complained actually just a vocal minority?

Hans, it's been a while since the last beta. Change few parameter names, add some dummy sliders to play with or even better - a SUDOKU easter egg...but please keep those good betas pouring in.

Phoenix: Working on the GAUSS value issue. And that turns out to be very difficult (but it's also one of the most important things that affect the low latency audio quality). |

Oh! reminds me of 3rd semester of my engineering course...IDCT, fourier transforms etc...  Surprisingly, I passed. Though can't remember if it was me who fared well in exams or was the examiner in a state of trance! |

Hope it'll work good. I have one special preset for US(75us) Low latency.

BETA601-018: - Dynamically adjusting audio transformation windows to better match the type of audio that comes in (A) - Dynamically adjusting clipping effectiveness to avoid clipping 'too much' in certain conditions (it's still not perfect though). (B) (A) reduces the artifacts caused by - mainly - bass sounds at low latency settings. This is only done if there is almost only bass in the audio, at a single frequency - at other frequencies changing the window shape has bad effects. The default window shape is very different from that of the previous BETA's, and much closer to that of version 6.00. When needed an extreme form of the shape from previous BETA's is selected. (B) allows me to change the window shape in (A) such that it causes less artifacts, without getting too much issues with deep bass and soft highs at low latencies. Notes: 1. Frequencies between 60 and 75 Hz are not handled properly yet, and can still cause vibration effects at soft high frequencies in latency 512 mode. (But FAR less than in version 6.00). Fixing this will probably increase artifacts for bass in this frequency range. 2. CPU load is probably a lot higher (haven't measured it yet) due to the dynamic adjustment of the behavior. The dynamic code was originally intended to be executed only once when a latency was selected, and it's not optimized at all. 3. I've tested this at latency 512, and there it helps. But I don't have a clue what the effect is on higher latencies. They might also sound better, but they could just as well sound worse. At latency 512, Steepness can now be set a bit higher than before because there are far less artifacts.

ETA601-018 [not available] Linux GUI version: http://www.stereotool.com/download/ster ... ETA601-018 [not available] What remains for 6.01: - Multiband: Adjust band 3 (and others?) 'soft limit' behavior at very low latencies. Maybe: Also check clipping (also for band 3, might be re-enabled!). DONE! 1 hour - Multiband: Adjust extreme EQ settings before processing to avoid issues caused by steepness. 1 hour - Multiband: Add 'Enable' button for steepness. 1 hour - Performance: Multiband steepness: Moving UP can be done inside current loop, no separate loop needed. Maybe down too. Currently Multiband is FAR more expensive than before. - DONE, solved in a different way. 1 day - Performance: Multiband: Remove sqrt(sqrt(cos())), pow(x, .75) etc. - too expensive, replace by lookup table. 2 hours - Reduce downsampling frequency because currently very high frequencies (21-22 kHz @ 176.4 kHz input sampling rate) in the input can cause spikes even if Hard Limit is used. 1 hour - And I need to check how much the performance is impacted by the latency improvements, in the case where no upsampling and downsampling is needed. This seems to be impacted way more than I expected (could also be Multiband steepness). ??? - MAYBE: Make Steepness smarter. That would much better preserve the audio, especially at very low latencies! How: Instead of setting all the levels at AT MOST the level of neighboring bands + a bit, combine adjacent bands, determine total output level, and then fix it such that this combined output level is approached more. (So one very low, one very high --> one a bit less low, one a bit less high instead of both low). - Fix NOISE GATE behavior in VST plugin - Fix 'red output bar' issue. DONE 1 day? - Attempt to set GAUSS back to 0 - gives MUCH better processing of most filters (no high frequency noise). BUT: Loudness effect in Bjork - It's Oh So Quiet - can that be resolved in another way? BUSY, 1 day? - Fix Highpass filter for higher input frequencies. - Chris: "I still hear diff on Bass and kick between Beta 16 vs Beta 08 on 2048 latency. I hear more bass and kick on Beta 08. Pls check!" Questions: * Multiband: Question: Is Steepness behavior ok? * Loudness: QUESTION: The changed Punch behavior, is that good or bad? Check: Check difference in behavior between 44.1 and 48 kHz input for multiband! This could potentially result in really big differences. |

Very good progress... i almost like some tracks more at 512 then at 4096... Since there is more work, in the meantime, i notice distortion caused by "Strict Bass Clipping /*Very" (some punchy bass) Test Track It's easy to note when is put bass at my amplifier to minimum. There is some similar distortion from Bass Boost too. |

If this what you're talking about?Test Track It's easy to note when is put bass at my amplifier to minimum. There is some similar distortion from Bass Boost too. - Bass pumps at the start of this track - Bass Boost on, 'Allow harmonics' frequencies higher than 'Then dropping to no boost' frequency. Example: 0/120 420/520 --> Does indeed sound very very bad. Effect starts to occur at latency 1024, but it very loud at latency 512. Loudness: Same track, everything turned off, Loudness at x1.01. No or low Punch -> no difference Punch at higher values -> Distortion at start. Also distortion in highs when bass is present! The odd thing is that Punch shouldn't be doing anything here, so this is clearly some kind of bug. |
