General Audio / Re: How can I find out the frequency/hz of this song?
Last post by hjlij -
I just registered to come here reply your question, I checked the frequency of this song, it is  480 hz instead of 432, again ,it's 480 hz ,it's not 432. if you have more question you could either reply here, or send me a PM

Would anyone be kind enough to help me?

I'm trying to figure out the frequency/hz of this particular song for my brother, but I just don't know how. I followed a tutorial on another website about how to do it using audacity, but when I tried it, the frequency seemed to be 108 hz, so I think I must have been doing it wrong.

I'm sorry to post this again, because I saw some other topics about it on here, but I just couldn't understand them. I'm really sorry, I know absolutely nothing about music, but it's really important to my brother and I'd really like to help him.

This is the song:

Can anyone explain to me, as simply as possible, how I can find out what frequency it is?

Thank you so much for reading.
FLAC / Re: Undithered digital silence causing problems

Those are not mutually exclusive.
4: Compile-time options that allow configuration of what is on or off on default? Maybe an idea in itself.
But once you allow for that, consider also an option --defaultconfig that switches off all compile-time configurations.

And still there can be a new option for --enforce-minimum-bitrate or whatever you call it, and a negative option.
FLAC / Re: Undithered digital silence causing problems

Most Windows software that I have, have no problem with this file, including Winamp native and old with the plugin, SMPlayer/MPV, Foobar old and new, XMPlay, AIMP, DirectShow/DC-Bass, iZotope RX5, OpenMPT, MPC-HC/old, MPC-HC/LAV, Reaper 6, SoX.
Then it is less of a problem than I feared.

Well such files should go into the testbench
Yes, seems like a good fit.

That points towards further restrictions to today's "Subset". More layers of strictness/laxness wouldn't be optimal, but if the mountain won't come to Muhammad ...
The reason I suggested it could be linked to using --lax is because this problem makes streaming difficult. Seeking is something that players must fix, but I think getting players to not stop playing because a buffer runs thin on a bitrate of 1.4kbit/s (that means a single TCP/IP packet of 1500 byte can contain more than 8 seconds of silence) is way more difficult. The goal of the FLAC subset is twofold: to enable streaming and to lower requirements on hardware implementations. This is clearly something that has to do with enabling streaming.

I see a couple of options
  • Link it to the usage of --lax, because it is streaming related. When someone uses --lax, the encoder no longer ensures no block with only constant subframes are created
  • Link it to a compression level. This can technically be done without changing the API/ABI, but this is not nice to users as they cannot choose for themselves to enable or disable it
  • Create a new option in FLAC and new functions in libFLAC API/ABI. While not really a problem, I prefer not touching the API/ABI when possible. It will also require modifying streaming server applications using libFLAC
  • Create a compile-time option, so a special libFLAC with this enabled can be distributed for use with FLAC streaming server applications. This can only be used for such applications where FLAC is dynamically linked (in other words, libFLAC is a dll or so)

The last option is probably the cleanest, and more or less what is happening right now as I asked a few people through github to test this patch for me.
