Audio Hardware / Onboard MB Sound vs Schitt Modi?
Last post by AudioNirvana3824 -
Hi, I'm wondering if I'd notice a difference between my Onboard sound from my motherboard vs an External DAC such as the Schitt Modi. I use to be an amateur audio engineer and have a M-Audio ProFire 610 from back in the day. So getting into external DACs interests me.

My chain is
Realtek ALC98 > Mini-plug-RCA > Source Switching Box > AudioSource AMP100 > Speakers
The AMP100 contains volume and balance controls so no need for a preamp. I'm on a fixed income so if external DACs are just snake oil please let me know. I'm a member of AudioKarma and folks there talk constantly of the noise problem in desktops.

Of course I could also just throw the ProFire in the chain and let it do the job. I have a new PC with Windows 11. I used to be a Linux user and the ProFire wasn't well supported under Linux.

Thanks so much.

I've been trying to find matching crash reports in Google Play, but they've done something weird with the system, probably to "protect privacy", and no useful info can be extracted whatsoever (no stack traces etc).
Maybe it's some bug that only shows up on Android 4.1.
Will the new release version actually still support 4.1 after Google has raised the minimum requirements?

Support - (fb2k) / Updating from older Portable Foobar 2000
Last post by renderMan -
Hello!

I have a pretty old Foobar2k portable version 1.6.16 and I would like to get it updated. I noticed there is no longer a portable download available. When I attempt to place the fb2k portable dir into my program files (x86) and run the newest foobar (32-bit) installer it will not work since it's the portable version that I have.

Any ideas how I can update it while keeping all the hard work I've done on my Foobar over the past 20 years?

I'm using Windows 11 Pro, 22H2, OS Build 22621.2283.

Error message:
The install directory 'C:\Program Files (x86)\foobar2000' contains configuration data, but foodbar2000 is not using portable mode. This is no longer supported since foobar2000 v2.0.

Thanks!

FLAC / Re: FLAC v1.4.x Performance Tests

Is it obvious that you should scan the entire file, when blocks are encoded independently?
Then the encoder would need to check for such redundancies for every block of incoming data, would slower than a full file scan.
[edit]
For example, clean 4x resampling often requires a digital filter that uses up to several hundred to thousand of samples. Which means, a sample at position n could affect other samples at positon up to for example n+/- 512 samples. By using a suitable apodization, the affected sample range can be greatly reduced. So when doing such analyses on the fly, the encoder always need to keep track of much more previous data, apply a math function to it to check for the suitability of a specific encoding strategy.

So, let's say a 3 minutes song works best with method A in the first minute, then method B and C in 2nd and 3rd minute, if these info are known, the encoder only needs to switch encoding methods at a specific time. A frequency analysis of the whole file is often pretty fast, for example, Spek.

Anyway, once someone wants to make anything out of a two-pass approach, then one could very well take a flac file as input
Then the previously encoded flac files can be used as a pass, but encoding from PCM or transcoding from other formats won't benefit from it.

So, who wants to do it? Multipass encoding is quite common in video codecs, which are usually lossy.

Some characteristics of a file can be obtained in a much cheaper way by scanning the whole file, like EBU loudness stats and this kind of resampling. It should be possible to make a separate app to gather these information then generate a suggested command-line batch file to feed the encoder.
So, those with skills, passion and patience can try to make such a 3rd party tool. Even if it is being built into the main project, it still requires a 2-pass approach.
Is it obvious that you should scan the entire file, when blocks are encoded independently? Sure if you find patterns that way, but ...
Anyway, once someone wants to make anything out of a two-pass approach, then one could very well take a flac file as input, read the predictor vector, and rather than starting to encode from scratch, (1) try to improve on the predictor that is already stored, and (2) keep it if one doesn't find anything better.

Cf. ktf's attempt at IRLS post-processing: IIRC, if the reweighting pass would not improve, it would be discarded in the end - unlike what I ahve seen with ffmpeg, where running more than a few passes would often make for worse compression.
