Interesting, I actually have that noise on some of my compressed tracks too (http://soundcloud.com/joshua_satterfiel … -stir-your). I would say just cry and/or use bandcamp.
edit: nevermind, great work ub
yeah it's irritating 
i'm curious as to exactly how much chipmusic ends up with this problem, i need to listen to more new stuff

soundcloud and bandcamp encode their mp3's from the lossless format you upload i believe. last.fm is weird in that it insists you upload 128kbps mp3's.
i was wrong, it actually says 128 is the bare minimum derp

Tested some encoders @ 128 kbps CBR 44kHz
The raw wave, perfect square:
LAME 3.98, surprisingly the worst of the bunch:
Fraunhofer FastEncc 1.02, not much better. I think iTunes uses this:
BladeEnc 0.94.2 was the best at this bitrate. Also surprising, considering it's bad rep and age:
As you can hear, the effect appears mostly with low to mid frequencies. Maybe I'll test a little with VBR setting later, just out of curiosity.
Didn't test XING because I couldn't find a stand-alone encoder and didn't want to bother to install some crap.
crazy, so the effect occurs with any sort of low frequency square waves i gather?

I got one that sounds fine. Gimme a sec to upload.

I just set your wav file to 48khz before exporting.
thankyou but my problem is with 128kbps MP3 as that's the standard for streaming online on sites like bandcamp. It'd be great if they could just stream 320kbps like your file as that'd help solve this problem but unfortunately i'm still stuck
Interestingly, i've tried every other pitch of the note within the octave and i still get a crappy transcode. I've also tried changing the envelope tail of the sound and i'm still getting bad transcodes. So at this point i'm guessing it's the actual waveform the gameboy is making that's causing transcoding problems. Gonna try out a few more things to try and narrow it down.

What's the sample rate? I had this issue with certain songs with LAME. Anything at 44.1khz would sound fine but songs at 48khz would manifest the exact issues you currently have.
i've tried 44.1khz PCM wav and 48khz PCM wav recordings, then rendering them to 128kbps CBR and the problem is identical in both D:

Re: wav to mp3 woes (28 replies, posted in Audio Production)
Thanks everyone for looking into this for me. I've heard this effect happen in a few of my recordings. I'm going to continue experimenting to try and narrow down the cause but i'm thinking it has something to do with those particular frequencies. Stereo imaging isn't a problem as i made the same recording without the effect and in mono and i'm still getting the 'aliasing' effect.
The reason why this is a problem for me is that whenever i upload to soundcloud or bandcamp, playing the sound back has this aliasing effect in it

Topic: wav to mp3 woes (28 replies, posted in Audio Production)
Hello everyone, i'm very new here, this is my first post on chipmusic.org, unfortunately it's cause i'm having tech issues
I've come across something infuriating in the music i'm making. Basically everything i record sounds fine until i convert it to MP3. Then something weird happens. Low frequency artifacts come out of nowhere. I'm linking to a rapidshare download of a zip file containing the original .wav recording and the mp3 conversion (128kbps CBR)
https://rapidshare.com/files/1418395871/wavmp3.zip
The recording is of a DMG prosound mod, then running it through a kaosspadmini with a reverb effect, then just recording straight into Reaper via line in on sound card.
My guess is that either the stereo ping-pong like effect is setting it off, or the low frequencies aren't agreeing with the conversion. Either way it's infuriating! Any help would be invaluable as i'm almost completely stuck on what to do.
(also the mp3 i attached is encoded twice - mp3 to mp3, which has highlighted the problem even moreso, maybe try converting the wav to 128kbps mp3 yourselves and see if you get the artifacts as well?)
