is there a script to extract, convert and remux all those stupid FLAC audios you see in anime packs now a day? I'm sick of this placebo shit.

Hearing the difference now isn't the reason to encode to FLAC. FLAC uses lossless compression, while MP3 is 'lossy'. What this means is that for each year the MP3 sits on your hard drive, it will lose roughly 12kbps, assuming you have SATA - it's about 15kbps on IDE, but only 7kbps on SCSI, due to rotational velocidensity. You don't want to know how much worse it is on CD-ROM or other optical media.

I started collecting MP3s in about 2001, and if I try to play any of the tracks I downloaded back then, even the stuff I grabbed at 320kbps, they just sound like crap. The bass is terrible, the midrange…well don’t get me started. Some of those albums have degraded down to 32 or even 16kbps. FLAC rips from the same period still sound great, even if they weren’t stored correctly, in a cool, dry place. Seriously, stick to FLAC, you may not be able to hear the difference now, but in a year or two, you’ll be glad you did.

Here, have a handy guide.

1: download a hardsubbed xvid re-encode of the show you want from TT. make sure it is a horriblesubs funimation rip.
2: encode it as 1920x1080x264. Open in in aegisub and add in some fabulous karaoke for all the insert songs.
3: encode it back to a 704x480 xvid
4: encode to 1280x720 rmvb
5: encode back to 704x480 xvid.Following this stage you can now decode it with 3 different codes for thrice the power!
6: open in vlc
7: take screenshots of each individual frame
8: record the audio to your phone
9: encode the audio from phone to a 7.1 flac to reduce rotational velocidensity
10: encode it again to q-1.0 vorbis
11: encode it again to 192kbps aac
12: make a slideshow of your screenshots with windows movie maker
13: add in your audio
14: add in some linkin park to play alongside the audio. It's like watching an amv!
15: use windows movie makers build in encoder to encode to youtube size
16: upload to youtube, add in loads of annotations and emoticons
17: download the .flv from youtube
18: open in vlc

I have a PhD in Digital Music Conservation from the University of Florida. I have to stress that the phenomenon known as "digital dust" is the real problem regarding conservation of music, and any other type of digital file. Digital files are stored in digital filing cabinets called "directories" which are prone to "digital dust" - slight bit alterations that happen now or then. Now, admittedly, in its ideal, pristine condition, a piece of musical work encoded in FLAC format contains more information than the same piece encoded in MP3, however, as the FLAC file is bigger, it accumulates, in fact, MORE digital dust than the MP3 file. Now you might say that the density of dust is the same. That would be a naive view. Since MP3 files are smaller, they can be much more easily stacked together and held in "drawers" called archive files (Zip, Rar, Lha, etc.) ; in such a configuration, their surface-to-volume ratio is minimized. Thus, they accumulate LESS digital dust and thus decay at a much slower rate than FLACs. All this is well-known in academia, alas the ignorant hordes just think that because it's bigger, it must be better.
So over the past months there's been some discussion about the merits of lossy compression and the rotational velocidensity issue. I'm an audiophile myself and posses a vast collection of uncompressed audio files, but I do want to assure the casual low-bitrate users that their music library is quite safe.

Being an audio engineer for over 21 years, I'm going to let you in on a little secret. While rotational velocidensity is indeed responsible for some deterioration of an unanchored file, there's a simple way of preventing this. Better still, there have been some reported cases of damaged files repairing themselves, although marginally so (about 1.7 percent for the .ogg format).

You know that would be a problem if people still used HDD's. Apple no longer exports in MP3, but is is still most compatible for most media programs. But you know having data loss over time only affect one audio file type is pretty bullshit. There is no program to actually playback FLAC, and the conversion is still MP3 bitrate for actual playback.

MP3 vs FLAC is nothing far from JPG to PNG
FLAC is lossless audio. Even if you leave it in a basement for a long time, the quality will stay the same. And probably major quality differences with studio-tier speakers/headphones.
>>
>>137630128
upgrade your audio rig and ears, and stick with 16 bit flac or higher. Any less than that and you don't need to bother, you don't deserve to listen to any music anyway.

A simple bash script with ffmpeg can do that no problem.
For example:

#!/bin/bash
#
for wav in *.wav ; do
cleanfile=${wav%.*}
ffmpeg -i "$wav" -n -codec:a libmp3lame -q:a 0 "$cleanfile.mp3"
echo "$wav" converted
done


Just replace *.wav with *.flac and it'll convert.

Oh right, you run shitty operating systems kek
