Does anyone know if AAC plus can be played by W800i and how do I actually convert AAC plus files?
I'm sure iTunes only does AAC conversion. |

W800 doesn't support aac+.
W900 does. (MP3, AAC, AAC+, MIDI, WAV, and XMF ) |

a bummer for peeps with all their music in omg format in sonic stage. However it's a lot better than making devices that ONLY support atrac, such as Sony have done until recently.
Atrac is a highly proprietary and closed format. You also cannot export ATRAC to any other format, courtesy of Sony DRM. AAC is a way better format. More flexible (not limited to three or so Sony applications for ripping audio), portable and non-proprietary. I believe it also produces much better audio quality at the same bitrates. |

In so far as I know, there is an AACPlus codec by dbPowerAmp. Maybe it only plays .aac Plus, but could also have a converter

well ive always been happy with Sony's products, from Minidisc to HiMD to their new HD walkmans, all of my CD collection was converted to mp3 first
But to me, sound quality is more important than how many tracks i can fit on it, i use 320Kbps mp3's at 44Khz. compared to other peoples ipods they all seem to have there music in a poor 'tape' quality 128kbs AAC.

I've always like Sony products myself. I owned the first NetMD model and still own a Sony Walkman (tape!), Sony headsets, and from SE, an HBM-30 (atrac/mp3 player combo bluetooth headset) and the K750 (with HPM-70).
Sony hardware is solid and always nice to use, and the only thing I ever really had a problem with is Atrac. It couldn't handle really complex audio pieces without weird compression artifacts (much worse I thought than mp3 and aac).
Atrac runs at 292Kbps in sp mode. MDLP2 runs at 132Kbps, and MDLP4 runs at 66Kbps. When I had the netmd, it was not possible to copy SP quality audio to the player without doing an optical realtime recording. So I never really got to listen to much SP audio.
The MDLP formats just didn't cut it and I eventually got sick of it and went to a full blown mp3 player. Much more convenient, and I could use any bitrate I wanted easily. |

i agree on the sounds quality however your not tied to 128kbs that would just sound better than an mp3 at 192kbs if you up aac to 192 or higher you get even better sound results.
also if size isnt an issue like it isnt for me apple lossless is simply superb sounding ,files come out at about 20mb a track but the result is so good its worth it |

back to the main point!
How do I make ACC + audio? |

Dreams, sorry buddy, but try Nero or dbpoweramp (both claimed on this site to be able to produce aac+ : http://www.mus-ic.co.uk/weblo[....]es/2005/02/aacplus_techie.html )
Arez, I wondered at that too.
Analog tape has frequency response 30-16KHz (compared to digital 20-20KHz), so there is a massive drop of audio data required on both ends of the frequency scale. Assuming the same sample rate when creating an AAC file, tape audio will retain more fidelity (to the original audio stream) than a cd pcm stream when ripped at the same bitrate. Therefore a lower bitrate can be used to retain the same fidelity as the AAC file ripped from cd at a higher bitrate. (but the audio quality is less due to smaller frequency response, and indemic noise). Basically this means you can faithfully reproduce TAPE audio in AAC format at lower bitrates than you would need to faithfully reproduce cd audio in AAC.
Not just this, but analog tape suffers massive loss of signal from noise, so even less bandwidth is needed to faithfully reproduce tape (if you run noise filters). So I guess from a technical point of view a 128Kbps MP3 would be about "tape quality" compared to "cd quality" 392Kbps MP3's.
But to be honest, I still have occasion to listen to tape recordings, and they aren't that bad. Infact due to the analog nature, there are some advantages to Tape over CD; the sound is fully and deeper and recorded on metal tape with dolby, sounds very nice. The reduced frequency response isn't as significant to listenability as many people claim.
But in terms of 128Kbps MP3 being equivalent to TAPE? Well such an MP3 still has the full frequency response of cd quality audio. MP3 (or AAC) codecs do not compress by throwing away higher and lower frequencies (unless you specify that). Therefore you cannot really claim that a 128Kbps MP3 is "tape quality"
Atleast that's my understanding, which I'm quite happy to be corrected on.

thanks a lot.. checking out on the software now.
One more thing. If SE were to allow.. and is it possible for them to add on media support for an existing phone model? Like W800i to be able to play ACC+?

unlikely. It may be 'possible' to install AAC+ codec via a firmware update, but I think these phones have the audio decoders embedded in the hardware, not in the firmware.

Oh well.. I thought firmware is just like an OS for the hardware. By updating the OS to do certain task we can totally change how a phone works. |

even if se could do it the question would perhaps be why would they do it. they would probably have to license the codec which costs them money and its still not a recognised codec yet so there not much in it for them from a business point of view
with firmware updates i prefer se to fix exisiting problems and not create any new problems |
