6/22/2023 0 Comments Bitperfect fixed indexing![]() ![]() Sound familiar? Direct indexing uses a similar approach to index funds and ETFs. How Direct Indexing Worksĭirect indexing involves purchasing the underlying securities that make up an index, with the goal of duplicating the index’s performance. This strategy is expected to grow 12.3% annually and reach $800 billion by 2026, according to a recent report from Cerulli Associates. Once the exclusive domain of wealthy clients, direct indexing has become cheaper and more accessible than ever thanks to better technology and ever-lower trading commissions. Rather than buying a mutual fund or exchange-traded fund, direct indexing allows investors to tailor their portfolio to their specific preferences and investment goals, and it’s especially useful for ESG investing. The default tries for 18 ms which is a bit too low.īut that's a great tip that will be useful to others, if not to me.Direct indexing is the construction of a custom investment portfolio that mirrors the composition of an index. The latency is 100 msec which is pretty bad, but I'm not a gamer so it doesn't affect me at all. However, by disabling timer-based scheduling and using buffer-based, I can increase the buffer size above the default and get higher latency with glitch-free audio. Incidentally, it's a fast machine (i7-4770 at 3.7 GHz) so it's probably an OS limitation not being able to schedule the interrupts reliably enough for low latency to work. So it's impossible to get glitch-free audio with timer-based scheduling on this machine. And in my case, the default buffer isn't big enough. But when I set bigger values, it ignores them and uses its default. When I set smaller values, I see it use them and latency goes down. OK so the problem with this approach is that you can make the buffer smaller than the default (196,608 bytes), but you can't make it bigger. However, if I can increase the buffer with the newer timer-based scheduling this is even better. It seems that firefox or chromium will pass through the file to pulse in its native format, and pulse will treat it the same way it treats a file coming from any other application, like a music player.Ĭlick to expand.Excellent advice! I was getting dropouts with Pulseaudio version 1.8, so I disabled tsched entirely and used fragments to increase the buffer to 200 ms. I have also successfully played 96khz files via firefox, for what it's worth. What this does is lower the buffer to 8ms, which is half a 60fps frame, so essentially real time. Load-module module-udev-detect tsched=1 tsched_buffer_size=2824 In addition to tweaking the nf file, I have configured default.pa by editing the line: Since I use my computer for things besides just music-listening and often have multiple audio streams open at a time, pulse suits me perfectly. I see no drawback of using pulse, unless you always use a configuration so simple that alsa can cover it painlessly. The feature-set is pretty much a superset of alsa at this point, since it will play any single source bit-perfectly but will also allow for playback from multiple sources at a time, or for automatically switching between configurations without fiddling with config files. But now that pulse has avoid-resampling, any time you play a single audio source at a time, it will do bit-perfect playback as well. It's bit-perfect by default and by design. Enjoy your music and love your dreams.Īlsa is nice because you know your music isn't getting resampled. ![]() If you are not susceptible to HiFi placebo you will be very satisfied. Voila! Welcome to the world of Audiophiles. Add the following settings to ~/.config/mpv/mpv.conf Step 5 - install and use MPV Player for Videophiles but also suitable for Audiophiles (in my opinion). ![]() But PulseAudio still interferes a little, therefore: Now by default Alsa try to use the same quality characteristics as the source. ![]() It is a raw communication without any conversions. #With the "hw" Alsa plugin we communicate directly with the ALSA kernel driver. Step 2 - buy one (used) Sennheiser HD598 (creamy brown) or Beyerdynamic DT 990 Black Edition 250 Ohm (less Beyerpeak than PRO). ![]()
