Hey.
The topic says it all: what is the maximum amount of bitrate this phone can play?

The maximum bitrate for an mp3 file can be 320kbit/s.

Yup 320 Kbps is the maximum for most mp3 software so I guess that's the maximum. They actually could have provided a higher value but that would give insignificant advantage IMO. The K700i can support all bitrates up to 320Kbps mp3.

best at maximum 192 kbit/s for local playback |

@Pow:
I guess you should use mp4 (80 Kbps) instead of mp3 because it takes less space (approx. 50% less) and is fairly acceptable in terms of quality.

Mp4 at 80 kbps? I wouldn't wanna listen to that ...
If you're only going to play it through the PC spekaer then I guess you won't hear much difference ...
i do not listen to mp3 lower than 192 kbps, and I prefer 320 kbps ..  |

The bitrate you use on an MP3 depends really on a number of factors:
1. What kind of music you listen to
2. Whether your ears are sensitive to certain frequencies - i.e. whether you would notice if a track was missing a certain frequency or instrument.
3. What you are gonna play the MP3 track on. Is it on a mobile, on a 5.1 Dolby Surround Speaker system at 100 Watts
4. What program/encoder you are using to do the encoding. If my memory serves me correctly, the encoder in dpPower AMP seems to be better than that in MusicMatch.
5. The file size you are after. A bigger bitrate results in a larger file.
6. And whether you choose to encode using Variable or Constant Bitrate also determines sound qaulity and file size, with Contstant Bitrate allowing you to guage more accurately what file size you will get for a given track.
For me, I like to hear a deep bass.
It is said that encoding at 128 kbps is akin to CD quality or something like that. Well I have found that I get better results at 160 kbps.
I don't like 128 kbps at all for it tends to drop some of the deeper bass notes.
The difference in sound quality between 160 and 192 kbps is not as great as the difference in sound quality between 128 and 160 kbps.
And for me there is the consideration of space so I find that 160 or 192 kbps at Constant Bitrate is a good choice for me in terms of sound quality and file size.
If all of your MP3's are gonna be played on a mobile phone, especially one that doesn't give a good frequency response through the headphones, then I see no need to encode your files in anything more than 128 kbps. That will give you reasonable sound at smallish file sizes. You can experiment with whether Varibale Bitrate or Constant Bitrate works best on your phone and headphones combination.
I hope my comments have helped.

if you want to have more mp3 on your k700i, try converting your mp3's into an FM radio quality, i think it's about 64kbps and it also sounds great! it only takes about 1mb per mp3! isn't that great, and you won't lose the quality you want. i save a lot of space by that! |

how do you convert to fm radio quality? |

first you need to decide the carrier frequency you're going to use, then modulate the signal using a voltage-controlled oscillator (VCO) ... 
seriously though FM radio signals can carry audio with almost CD quality if the transmitter and receivers are good and the signal is good. I agree though that 128 Kbps is not so good to a keen audiophile, 160 is fair and 192 is good.
I generally use 128 Kpbs mp3s for stereo playback on my sound system as I find it a practical balance between quality and size - I have a collection of more than 40,000 songs already so size is a really big factor for me. For my K700, however I use mono mp4s at about 56Kbps so I can store more with the limited memory.

i like higher bit ratres. about 192.
(this has nothinbg to do with phones, but i have a Creative Sound Blaster live 5.1 card and a Cambridge Sound Works 5.1 2000w digital speakers.  )

MP4 ACC 128kbps is comparable to MP3 192kbps and it uses 1/3 less space. |
