But, if you're using the same bitrate, higher sampling rate means lower quality. You have a different opinion and that's not a problem for me. Also, 11025Hz is a medium sampling rate for me.

It's not my opinion, it's a fact. But that is not important now. If you are satisfied with 11025 Hz sampling rate and muffled sound, that's okay.

In my opinion, you are an atom slightly outside the Schwarzschild radius of a supermassive black hole at the edge of the observable universe.
You are of course entitled to a different opinion, but they are all opinions and thus none are more wrong than the other.

A more relevant opinion is that TOS#8 has been inadequatly worded from the dawn of HA time.

I did an ABX today, remember.

Just out of curiosity, what is a low sampling rate for you & also what is a high sampling rate?

It is easy to fake a null result. If you pretend not to hear the difference between 8 kHz at 32 bits and 16 kHz at 16 bits, nobody can force you to actually listen instead of clicking at random.

5512.5Hz is low, and 22050Hz is high for me.
May I kindly ask how old you are? I am 65 and can clearly hear a difference from 22050 Hz to 44100 Hz.

I'm much younger than you, but that's not the problem because I can hear the difference between 22050Hz and 44100Hz too. I'm not in a search of "fidelity", I'm in a search of a "warmer" sound.

11025Hz does not sound like muffled to me as I use linear interpolation. You should give it a try.

Use bad resampler to compensate for bad encode?

You seriously think that a 16/16 disproves differences?



A 16/16 ''proves'' differences.

And so your argument that sampling rate does not affect quality, is not in any way supported by anything you try to bring to the table.

I posted a downsampled file at https://hydrogenaud.io/index.php/topic,126168.msg1046984.html#msg1046984 .
Isn't it clear that it is bad quality?

11025Hz is not a bad sampling rate for me, and linear interpolation is not a bad resampling method for me. By the way, did you know that most Flash games were used 11025Hz 16kbps mono MP3's and resampled them with linear interpolation? This is the default audio format of Adobe Flash. If you want to see a game that uses this sound format, go to https://archive.org/details/tails-nightmare .

I'm looking at quality from a different viewpoint, please respect to my opinions.

Here at HydrogenAudio, high quality means "perceptually indistinguishable from the original".

Not necessarily. "Perceptible but not annoying" is not the worst: https://hydrogenaud.io/index.php/topic,125899.msg1044043.html#msg1044043

But sacrificing an audible octave or more just in order to boost bit depth to 32 - and claiming it improves - that is kinda ...

@shadowking Do you know how can I export a raw AAC (.aac) file with qaac, and use the --lowpass setting with it (it says it requires libsoxconvolver but I don't know how to install it)?

This sound is not the result of just the encoder. It's bass boosted, bit crushed and heavily equalized/DSP'd to sound like that.

Why do you think it's bass boosted, bit crushed, and heavily DSP'd? I compared it to the original music and I did not see any signs of bass boost, bit crush, and heavy DSP effects.

I found how to install libsoxconvolver (topic#116598) but I still need to learn how to export a raw AAC file with it or convert a .m4a file to a raw AAC file.

But, I still can't apply a custom cutoff. Does anyone know why?

What cutoff are you trying to apply and how are you trying to apply it (command-line example)?

I want to apply lower cutoffs for some bitrates and higher cutoffs for some bitrates, but I could not. Here's an example command that I tried to export a lower cutoff (I don't want to use that low cutoff, this is just for testing): qaac -c 24 -r 22050 --lowpass 2000 sh44m.wav
