I'm noticing an echo effect in the playback especially during quieter sections of music. Is there a way to make this go away?
Thanks.

Do you play your music with any DSPs "or" equalization active? If so, try disabling them one by one and see if your problem disappear.

Hey - thanks for the quick response!
I just installed the program, and am using the default setup - no active DSPs and equalizer is not enabled.

But the echo is still there... very quiet most of the time but screwing up the sound of some sections of songs.
I don't want my audio player deciding how the music should sound!

Could poor playback quality be due to the codec I am using, or the driver I have installed for my sound card?

I didn't have this problem with iTunes, and I am wondering if there is some sort of codec or driver that comes with it that is appropriate for .m4a files or something... many of my audio files are in AAC format. I MAY be noticing a difference in quality between AAC and MP3 (MP3 sounding better).

Any thoughts?

We won't know until you try some ABX testing.
Unless this "echo effect" is unmistakable, it could just be that you're making something up. wink.gif


However, if you're using XP, you might first try using the Kernel steaming output component and see if that helps, before spending a bunch of time doing ABX testing.

Thanks for those links.
I don't think I'm making anything up, but I may be describing the symptoms rather poorly. An echo is part of it, but not the whole story. Basically what I'm looking at is that when I play AAC files (as were imported when I still used iTunes) they sound "low-res" if you can use a term like that on audio. It sounds like a poor internet radio feed or something like that... I don't notice this when I listen to MP3 files, AND I didn't notice this when listening to AAC files with iTunes.

SO, is there a specific audio "decoder" for AAC files that I need on my computer to have them played at the best quality possible? Could this decoder have been deleted when I kicked iTunes off my computer?

I'm gonna try converting some of the m4a files to mp3 and see if the sound gets better...

Sorry for my extremely ignorant questions. and thanks for helping!

It won't, both are lossy compression formats. They achieve a size reduction by leaving out audio information that they estimate to be inaudible.

If you want a really silly analogy: It's like pouring water from a yellow bucket into a red one. The water won't get any wetter, but you might spill some of it in the process - especially if the red bucket is smaller.

Gotcha.
I kinda figured that would be the case, and the fact is the two file types sounded the same once I gave it a try. It does prove (I think) that what I'm describing has nothing to do with how the two file types are being "read" by the player, though.

I am tempted to re-install iTunes to see if I am just making stuff up. If the same songs sound different when played in iTunes, I will have to figure out what is going on inside the circuits of my poor computer.
