3rd Party Plugins - (fb2k) / Re: foo_random_pools
Last post by Ryrynz -
Just trying to figure this out, I have a random pool called Anime 3+ which looks to select a bunch of random anime style songs that are rated 3+.  In Filter I have %Genre% HAS "Anime" AND %Rating% GREATER 2 and Number of Tracks to add is 5. If I click File - Random Pools Anime 3+ I get 1-5 tracks and they're not random at all, most are from the same album.

Audio Hardware / Re: USB-I2S chip 32bit 384khz

24-bits gives you 144dB of dynamic range.    That's more than you can practically use...   On they loud-side you're above the threshold of pain and hearing damage (if your system can go that loud) and on the quiet-side you're below the environmental background noise (or below the threshold of hearing).

32-bits gives you 192dB of dynamic range which is of no practical use.    There's no issue on the "digital side" but you'll never get that kind of range on the analog (or acoustic) side.
Doug, I believe using dB units while talking about dynamic range can be very confusing as most people associate dB with loudness.

I think if someone is confused by units like dB, they're probably not going to be reading this old thread you bumped about DACs.

Doug, I believe using dB units while talking about dynamic range can be very confusing as most people associate dB with loudness. In reality, it's just a unit that measures a ratio between two values.
Let me explain this in more details...
24 bits gives you 2^24=16,777,216 values to represent your analog waveform (that has values from Vmin to Vmax in Volts).
The dynamic range is the ratio between the largest and the smallest digital values and in this case is equal to 16,777,215/1 or you can represent it in dB units using the following formula: 20*log(16,777,215/1)=144 dB. That is just a ratio and it has nothing to do with the sound that has the loudness of 144 dB!
Whether you have 16 bits or 24 bits or 32 bits, you still represent the same analog waveform that goes from Vmin to Vmax in Volts. So using different bit depth won't make your sound louder - it just means you have more resolution for the amplitude of the same standard volume range.
I hope that helps!

Audio Hardware / Re: About best earphones which are durable and with lowest radiation.
Last post by andy o -
I can't think of any other way to get harm from listening to music with earphones or headphones other than having the volume too loud. You don't need to worry about any "radiation" in any case, wired or wireless. Some people may claim that Bluetooth or WiFi, or cell signals cause sickness or even cancer, but I'm not sure that's what you're talking about, and it's not true anyway. It's an old myth by now.

FLAC / flac or mp3 or bad master?
Last post by airtas -
I purchased a FLAC album from Tidal.  The album is a digital album only.
The artist added two b sides which I had prior as an mp3.
AuCDtect said the source of the two files was mp3.

It seems the cut off is around 16 khz but the spectrum also goes into 22.

Are we thinking this still isn't a flac because the cut off occured at 16?  Why is some of the music hitting 22?

Flac 1 and 2 files are the ones in question.  Flac 3 seems to have more detail and is labeled as CDDA as the source in AuCdtect.

I have also shown the mp3s I had prior.  The "Flac" seems better but maybe not?
