iPod mini 2G stutters when playing LAME aps

Any update on this issue?

i was going to ask the same. i'm about to buy a nano, but i would have to buy an iAudio if LAME works bad.

EDIT:

- problem go away when using an EQ setting different from flat/off
- only safe EQ setting to use is Bass Reducer / Treble Reducer in order to avoid distortion of songs with a high recording level
- for the 4G color iPod only the sample with NIN - Right Where it Belongs stutters, even with the EQ set to Bass Reducer. Acoustic EQ setting makes the problem go away.

sorry for the question, but i'm yet to onw an iPod, does the Bass/Treble Reducer EQ settings change the music much? i mean, if that fixes the problem, why don't use it?

I've just bought a Video Ipod 60G and I'm having problems with two songs:

- Madonna / Hung Up
- Cold Play / Fix

Both files were encoded with Lame 3.97 b2 VBR and I get distortion in both.

So, I ran mp3gain and both files had a lot clipping. With this tool I gave both files the right db (89), but they are still clipping on my ipod. Definitley I can hear A LOT of distortion. I will try to encode them in AAC to see if Lame is the problem.

I have heard that this fixes the problem...but my problem still exists, even with the use of the EQ settings...

Madonna's - Hung Up is supposed to sound distorted. 
The distortion is the same as on the original. E.g. from 2.45 to 3.00 in the song it is very noticeable.

If the second song you refer to is Coldplay - Fix You, I can't hear any added distortion in the encoded version either.

IMHO you should be happy that you can now hear details of the original production that previously went unnoticed.

it's either meant to be or try to turn off the EQ
--alt-presets are there for a reason! These other switches DO NOT work better than it, trust me on this.

That is not related to this problem. This problem is actual skips in the songs, not distortion.

I'm very happy with my new Creative Zen Micro here.

No problems playing my VBR MP3's, and it's gapless (or very very VERY nearly so) too.

Sorry to hear about all you guys having trouble with your iPods.

isn't it kinda off-topic?

No, not at all. If anybody here has trouble with the iPod mini and their VBR files, they should exchange it for the Zen Micro. With the exception of AAC support, it does everything the iPod Mini can do. Lend me an iPod Mini for testing and I can tell you in what ways the Zen Micro even outperforms it.

The thread itself is off topic by the way (belongs in Audio Hardware, not MP3 Tech).

An iPod circle jerk party... I'd rather stay home.

Matter of fact: If you buy something and it doesn't meet your needs/expectations, you stand a better chance at buying something else that will, than getting any change.

Just tried the new firmware on my iPod mini 2G...

Bug not fixed. 

This is the second update made by Apple after the stuttering issue has been reported.

One could speculate that the issue is a hardware issue with the processor that apparently calculates the clock speed wrong when playing back mp3.

Would still like to hear whether the bug is still present in the nano too.

iPod nano with new 1.1 firmware still stutters.  In other words, Apple will never fix this.  Good times...

Yeah that must be the reason. Or, it could simply be a limitation with its decoding chip. That could explain why it's not a problem on the new video iPods

Limitation with its decoding chip? No freaking way, and the fact Rockbox developers have already started the porting process confirms this quite enough.

The other thing is that if Apple releases another firmware upgrade that fixes the stuttering problem, it'll reduce processor throttling, which may (and possibly will) lead to a reduced battery life.
And that kinda contradicts with one of their marketing statements of increased battery life (12—14 hours is already pretty bad for a flash player, they can't afford themselves to lower this value any more).

AFAIK, video iPods have more capatious battery.

I think the iPOD's only really aimed at playing AAC files downloaded from the iTunes store so why would an mp3 bug limited to a non iTunes encoder be a priority for Apple?

That's Apple's main excuse, yeah.

What issues? When I got mine it was full of bugs (channel swap, 'tick' between songs, not turning on and frequent crashes etc). These were all taken care of in a subsequent FW update.

If they didn't know/care about the skipping problem, then why was it fixed on the 5G iPods?

might have happened by chance due to different parts or they fixed it so they give people another reason to upgrade. It is also a difference if you design a product from scratch or eliminate bugs for an existing product that has been superseded.

It's not "every song", it's a select few... and it's very irritating.  Yes, using the latest LAME 3.97 at -V2 or -V0 & --vbr-new.  Which songs are impacted may depend on the version of the encoder.  And as most have said, it's somewhat related to the bitrate changing significantly.
