how to get the best audio. e4u68


there are three ways to get audio
  1. rip from a source (usually a game)
  2. rip from streaming services
  3. cd-rip.
let's look at each of them.

    1. rip from a source - the audio source, dance with tambourine over the audio files,
      follow Algorithm 4, ???, PROFIT!!!
    2. rip from streaming services - flac from here https://free-mp3-.net/, follow algorithm 4, ???, PROFIT!!!
    3. cd-rip - private invite-only sites (you know what i'm talking about, jpops***) or SoulSeek. f/e: SoulSeek, look for flac there, and the same procedure as above
    Algorithm 4 - Open Audacity, export your audio there, convert to OGG Q6.
    If MV bitrate exceeds 192 kbps - follow Algorithm 5 instead of Algorithm 4.

    Algorithm 5 - Please, don't make situations when mapper is using audio from one album and you give him audio from another one, they have different mastering, and it sounds very different... You know, BN's won't be happy about it.



how to check audio correctly 2d5u3j


it's very simple here. if mv doesn't detect anything - follow instructions below
spek, open it to full screen and look at the spectrogram

if you have a .mp3 of 192 and the spectro looks like this \/

it's quite rankable audio, don't touch it unless you want to give better audio (if you can)

that's good lol

if you have a .mp3 of 192 and spectro looks like this \/

it's a bloated 128 and you need to find a better one

mp3:
128kbps audio: cutoff on 15.8-17khz without any frequencies higher at all.
192kbps audio: cutoff on 18khz and higher

ogg:
ayy lmao
there is no way someone would overencode ogg, right?)

feel free to correct me and give any suggestions.

as i tested, konmai game files don't need any tambourine dance and you can just export .s3v (sdvx) or any other file to audacity

it's bad to transcode mp3 -> ogg. don't do it if you can get .flac.
in other case... well.. use mp3 vbr

Algorithm 6 - if your audio bitrate is 193-195kbps by MV, it's kinda acceptable to add a liiiiiitle silence in the end to trick it.
it's really not recommended but it's situational. at most situations it's just better to reencode your audio with VLC (algorithm 5)
huge disclaimer

spectro is not a reliable way of determining audio quality outside of LAME encoded MP3s z102c


free-mp3-.net gets their audio from deezer

the best way to check audio quality is to listen attentively
