FLAC is totally lossless. You can rip a CD to 44kHz WAV, compress it to FLAC, and then decompress it and get a bit-perfect copy of the original WAV.

Lossless converting a CD to FLAC. But that CD was recorded at 44hkz sampling rate, which gives you a maximum frequency of 22khz. You have lost audio above 22khz. Children can theoretically hear frequencies higher than this, but typically adults cannot.

FLAC doesn’t cut anything out though. Whatever input you use, FLAC compresses losslessly. You can use 96kHz 24bit recordings and the resulting FLAC file can be decompressed back into a bit-perfect copy of the original.

In the OP, the messages in red are correct. FLAC is like a ZIP file designed to be more effective at compressing audio files. And just like a ZIP file, you can reconstitute the original file exactly. There’s no data lost in compression.

Yes if you’re transcoding a CD to FLAC it’s lossless. That’s not what I’m talking about. I’m talking about the process of digitally recording the audio in the first place.

Nevermind the fact that nobody seems to have paid any attention to the original joke which is that the boomers who can afford high end stuff can’t even hear the difference.

Posting guidelines.

All posts in this community have come from elsewhere, it is not original content, the poster in this community is not OP. The person who posts in this community isn’t necessarily endorsing whatever the post is talking about and they are not looking to argue with you about the content in the post.

You are welcome to discuss and debate any topic but arguments are not welcome here. I consider debate/discussions to be civil; people with different opinions participating in respectful conversations. It becomes an argument as soon as someone becomes aggressive, nasty, insulting or just plain unpleasant. Report argumentative comments, then ignore them.

There is currently no rule about how recent a post needs to be because the community is about the comeback part, not the topic.

Rules:

• Be civil and remember the human.

• No trolling, insults or name calling. Swearing in general is fine, but not to insult someone.

• No bigotry of any kind, including homophobia, transphobia, sexism and racism.

• You are welcome to discuss and debate any topic but arguments are not welcome here. I consider debate/discussions to be civil; people with different opinions participating in respectful conversations.

• Try not to get too political. A lot of these posts will involve politics, but this isn’t the place for political arguments.

• Participate in good faith - don’t be aggressive and don’t argue for arguements sake.

• Mark NSFW posts if they contain nudity.

• Satire is allowed but please start the post title with [satire] so other users can filter it out if they’d like.

Please report comments that break site or community rules to the mods. If you break the rules you’ll receive one warning before being banned from this community.

This community follows the rules of the lemmy.world instance and the lemmy.org code of conduct. I’ve summarised them here:

  1. Be civil, remember the human.
  2. No insulting or harassing other members. That includes name calling.
  3. Respect differences of opinion. Civil discussion/debate is fine, arguing is not. Criticise ideas, not people.
  4. Keep unrequested/unstructured critique to a minimum.
  5. Remember we have all chosen to be here voluntarily. Respect the spent time and effort people have spent creating posts in order to share something they find amusing with you.
  6. Swearing in general is fine, swearing to insult another commenter isn’t.
  7. No racism, sexism, homophobia, transphobia, xenophobia or any other type of bigotry.
  8. No incitement of violence or promotion of violent ideologies.
