As those of you who have used them know, the Tadeevo Bliss are the greatest shoes in the world. The 5 mm ultra thin, perfectly flat sole, virtually zero artificial sidewall support, super thin grippy textured footbed, make these the best shoes you can wear with socks. I have tried the Xero Speed Force ii, Merrell Vapor Glove 4, 5, 6, and even Vibram's most minimalist model, the Graspifier. Nothing comes anywhere close to how minimalist the Tadeevo Bliss is. I am not affiliated with Tadeevo in any way. Their Bliss shoes are just so good, it's beyond my imagination how this is not more widely realized.

Lately I tried the Magical Shoes Roma sandals, but found them ultimately worse than the Tadeevo Bliss. When I realized Tadeevo also made Sandals, I was thrilled, but I soon learned that they only offer up to a size 41 cm in them. I wear a size 44 cm (US M11) for the Tadeevo Bliss.

Do any of you know any sandals with similar quality to them (link to picture)? They have the same 5 mm ultra thin sole as the Bliss, with insane flexibility and durability. I literally cannot wear any footwear besides Tadeevo for extended periods of time without getting annoyed.

The grainy leather footbed seems better for footbed moisture dissipation than smooth leather footbeds.

Also, the toe peg looks more comfortable than other huarache sandals.

The CrinEar reference makes a lot of promises, largely based on pseudoscience, which I dissect and analyze in this video.

The Low-Frequency Effects (LFE) channel is defined up to 120 Hz and is already low-passed at 120 Hz in Dolby encoded content. However, not all content follows this standard and can have extreme waveform clipping when digitally analyzed. Most people likely wouldn't even notice this due to their subwoofers not going high enough in frequency.

When including the LFE channel in headphone playback, applying a low-pass filter becomes necessary to make this clipping inaudible. Since the LFE channel is typically defined to 120 Hz, I want the filter to be 0 dB down from +7.1 dB in the passband (left or right channel: summed LFE stereo output = +10 dB in passband relative to single channels).

I also want to filter out unnecessary content above 120 Hz to prevent artifacts that weren't heard by the mix engineer in the first place.

The red curve shows the FIR low pass filter Dolby uses in the Dolby Atmos Renderer for the LFE channel. Since they implement it as a linear phase filter, the rest of the channels must be delayed by about 20 ms. The filter is significantly down by 120 Hz and can blunt the transients of the LFE channel for well encoded/mixed LFE content (any Dolby Atmos production).

I'm implementing the green curve as a minimum phase approximation of a 10239 tap FIR "monotonic" filter. It's perfectly flat to 120 Hz and -60 dB at 150 Hz. Using a phase fit band of 20 to 100 Hz (I tested 20 to 60 Hz, 20 to 80 Hz, and 20 to 200 Hz as well), I calculated a ~8 ms delay to add to the rest of the channels so that the combined output sounds as similar as possible to using no low pass filter for low pass filter encoded content.

What low pass filters are the rest of you using for your low frequency effects channel (if any), are you implementing it as a linear or minimum phase filter, and if minimum phase, how are you determining the optimal time delay for the rest of the channels (i.e. latency and processor constraints)?
