    Sound quality using a ipod interface?

    I have a pioneer avh-p7500. See below.


    I want to use this

    http://www.pioneerelectronics.com/PU...-IB100II?tab=A


    But iam concerened with the sound quality. I know the actual song itself plays a role, but iam planning to sync my cds onto my ipod and use it through my pioneer HU. For those that have this interface, is the sound quality the same, or do you notice a difference? Because i dont want to lose quality since i have an upgraded system.

    Thanks guys.

    I use my iPod and I can't really say I hear much of a difference.
    My old iPod was quieter, but it was like that in all applications. Ishy hardware I guess.

    But iPods convert your CDs to .aac format, which is just Mac's version of Mp3, and will run at whatever bitrate it was originally ripped from. (Average quality is about 192Kb/s).
    So, it all depends on the quality of the song.

    are CD's 192 or 256 or something?

    i thought that they were a tad higher, but i could definitely be wrong.


    but to OP, yeah i use a hard drive and dont notice any difference lol, it sounds just like a CD but i download music using napster legally and CDs.

    Re: Sound quality using a ipod interface?

    I always thought CD's were like 1028 kbps or somewhere right over 1000.

    I also thought Ipod's converted everything down to 128, except for that "itunes plus" feature which allows your songs to play in 256? Is that right?

    That would explain why all my high bitrate songs sound like poo...


    I think CD's are 192.... But it is an unaltered copy, no alterations or anything.

    Re: Sound quality using a ipod interface?

    For CDs: 16 bit * 44.1 kHz * 2 channels = 1411

    ETA: With that said, I have been converting to Apple Lossless and I can't tell the difference between the ipod or a CD with the same material sitting still, much less cruising @ 70 MPH on the interstate!

    i have that for my 880prs...sounds the same as a cd depending on the mp3 quality

    all my high bitrate mp3s sound just like the cd....r u sure they are converted down to 128?

    EDIT: i jus google it it n i think there is an ooption to make it down convert them but it doesnt do it automatically

    Re: Sound quality using a ipod interface?

    You have to tell it to down convert. With 99&#37; of the systems out there you won't hear a difference between the CD and an mp3 with a 196 or above bit rate using the dock connector. Using a 3.5mm headphone adapter is a totally different story.

    Never underestimate the power of stupid people in large numbers.

    Re: Sound quality using a ipod interface?

    the frequency response when using an ipod and the pioneer interface will be perfectly flat. just like it should.

    as long as you use a high enough bit-rate and use the "flat" setting in the ipod's EQ then it'll be tough to tell the difference.

    here is the little test i did: http://www.caraudio.com/forum/showthread.php?t=354338



    07 Scion tC: 880PRS, ID OEM 6.5" mids, Seas neo alum tweets, DD S4 and DD C2a amps, Dayton Ref H.O. 10(.7net, tuned to 30hz)

    HT: Samsung PN58B560 - 80gig PS3 - Yamaha RX-V2500 - Infinity Alpha 50 mains - Alpha center - Harmon Kardon HKB6 rears, Epik Sentinel & ED eQ.2.

    That is not correct, it is wrong. You choose what quality you like, it's up entirely to you when you rip. You can have from no compression AIFF files, Apple lossles and down to measly MP3s if you like, but nothing is done by automatics.
