I was listening to my music on my iPhone and when I started to listen to it closely, it sounded gritty and wobbly like it was from a cassette tape. Of course the song wasn't ripped from a cassette, nor am I listening to my iPhone via a cassette tape adapter. Does anyone know why this is? P.S.-When I listen to the same song on my laptop, it's fine. alt text

try converting it into a different format.

I recommend standard MP3 as well as uncompressed wav

Gracias! In order to fit all my songs into my iPhone, I need to convert it to the AAC/M4A format at 128kbps. Sucks don't it? I don't think the iPhone supports .wav files. You think the reason is because it's in that format?

I haven't tried .Wav files on my iPhone, but you could test out ALAC and see if the problem persists. If all else fails you could go get a LOD>3.5mm cable and a portable headphone amp(CMOY amp or Fiio E7). Doing that will bypass the iPhone headphone amp and possibly fix that issue, but if nothing else it'll give you better audio quality.

^Seems like a lot of work, lol.

with high compression you mainly lose details in the highs and may introduce static like distortion with extremely complex sounds (eg heavy metal). The compression should not introduce unevenness, eg random changes in pitch or speed.

128k should sound fine for mobile devices and you shouldn't notice the difference unless you are using quality headphone.

Psssssh, I don't count a $25 pair of JVC's quality.. I call them great, but not "professional". And yeah, I mean when I listened to this track, he started to sing in a higher pitch, and I heard the guitar was wobbly. This sucks when you're in your zone singing with the song, lol. I'll uncompress all my songs then, thanks for your info!

I have never had pitch problems with music unless I compressed down to around 32kbit/s

128k should not be giving you any problems

are there any alternative audio players for the iphone?

For my mp3 player (sandisk sansa fuze (got it because it was cheap and could be used without taking it out of your pocket since it has physical buttons) I use 128k mp3 audio. Sounds decent enough, no need to use 320k or flac.

(some people do that, you generally know when you see someone walking around with $200 headphones, ignoring the fact that you would not spend $200 on a headphone and waste extra space on uncompressed audio if it made your music sound like their was a bus in the background.

Anyway, for music, the lowest you can go is generally 96k (works music with simple sounds, (no dub step or heavy metal), 128k works well for most audio, and 256-320k is useful only for the most demanding songs with a ton of different sounds taking place in multiple frequency ranges.

If you have a case, it could be filtering the quality sound and turning it into "bleh". Or is it only that song? Because I know that with some cases, the speaker compartments are not finely crafted and they make it sound like a tin can. Kind of like some monitors/displays.

It's maybe like 5-10 songs, not the whole library, lol.
