t-money Posted December 20, 2011 Report Share Posted December 20, 2011 i have checked several phones with o-scope just cuz i was bored. and all of them put out a hideously nasty signal even at low volume. cd or USB is the way to go Quote 2002 ford focus hatch pioneer DEH-P8400bh infinity kappa 6.5 components front and rear XS Power D1200 Shuriken BT-100 audioque 120.4 2 15 inch audioque HDC3 D2 2 audioque 2200d big 3 mechman 220a alt with external regulator 479-418-3056 Link to comment Share on other sites More sharing options...
tlee2 Posted December 20, 2011 Report Share Posted December 20, 2011 Nearly every device with a headphone jack output will clip. All iPods will at max volume, I'd bet that all Blackberry's do, probably all the Android phones as well. The digital to analog sound processor in these devices is powered by a tiny little battery, not the most powerful thing in the world. I've always found that 85%-ish is the point where I can't hear any distortion on my iPod with a flat EQ. However, I've also noticed that off an iPod there's much weaker bass than off a CD or USB drive. After grabbing a flash drive for my car I haven't found a need for CD's or my iPod in the car anymore. Mines the opposite mine is louder off my ipad via aux. then cds are. I cant even drop my voltage under 13 with 2 saz 3500s and stock alt with my cd player (honestly) i sure as hell can with something thru the aux input tho Quote 6 Sundown X 15s 2 Sundown NS1 V2s C Pillar 4th order Bagged Suburban on 24s http://youtube.com/tlee333 Link to comment Share on other sites More sharing options...
CHEVY4X4BLAZER Posted December 20, 2011 Report Share Posted December 20, 2011 I noticed that songs on the radio hit better than on my phone or mp3. Quote Link to comment Share on other sites More sharing options...

If you burn a 320kbps song on a cd it doesn't change the quality. Quote Link to comment Share on other sites More sharing options...

But after reading this thread, It makes me cringe even more at the thought of using my Aux jack on my deck. It should be ok at low levels though right?

Maxim Posted December 21, 2011 Report Share Posted December 21, 2011 (edited) MP3's off an iPod's dock connector to USB will be the same as MP3's off a flash drive and will be the same as the same MP3's burned onto a CD. Burning an MP3 onto a CD doesn't magically up the bitrate and make a higher quality audio recording. It just writes whatever data is there. WAV will generally be a better bitrate as it is uncompressed (unless someone decided to lower it to reduce file size) If you have your iPod at full volume through the AUX input, it'll be louder bass because it's actually a higher amplitude sine wave than the unamplified file off the CD. The "volume" knob on your iPod is a gain knob for the internal amplifier. Nothing more. The trade off is that the audio is now most likely a clipped signal. The same effect as turning the gain knob on your amp to full. It will be loud but it's risking damage to your equipment. A small amount of clipping is fine of course but if you haven't used a DD-1 or o-scope to set your gains then your iPod is clipping plus your headunit at full volume could be clipping and possibly your sub amplifier. 3 potential sources of distortion simply compounding on one another. If you're going for best quality, stick to .wav files on a flash drive/iPod via dock connector or use CD's. Edited December 21, 2011 by Maxim Quote wtf is lolcats? I'd def get a fat hooker if i had to resort to that kinda thing. I feel like they'd be grateful and work harder. Also its more bang for my buck, more real estate for my dollar if you catch my drift. its like the Costco of streetwalkers. I was hoping for 150 .

Lucky4Designs Posted December 22, 2011 Report Share Posted December 22, 2011 I found out my CD's really don't bump as hard as my iPod does. Now with the aux cable into my iPod with the volume at about 80-85% on the iPod, the output is completely different. I can actually get my (well, what used to be anyway) back windshield to flex. It does help to have a very high quality aux cable as well, I took one from my computer and compared it to my Griffin cable and the difference is night and day.

EVAlonSo Posted December 22, 2011 Report Share Posted December 22, 2011 (edited) ipods and iphones used through USB are interfaced. the radio reads it off the unit sort of like a CD unlike aux where it replicates the sound. itunes claims their songs that you download are "lossless" and are CD quality.

It is actually the opposite... Most of their songs are not cd quality and are usually a low bit-rate. Quote Link to comment Share on other sites More sharing options...

In regards to bitrate, I've always ended up with 256kbps from iTunes. But I don't think I have ever seen iTunes claim their songs are lossless.
