codec for "mpeg layer 3" setting

[sway]

Hi, need some help with codecs, i dont have the mpeg layer 3 option when i want to convert mp3 to compressed wav ... i know i need a codec, and i have followed all the help on this forum with no success. i did at one point have the mpeg layer 3 option after installing a lame codec, but when converting DBPowerAMP just crashed.
Any help greatly appreciated, ive been struggling with this for over a week now :cry:

that was the codec i installed, it gave me the mpeg layer 3 option, but while converting it just kept crashing dbpoweramp (while converting it would just close)

disregard last post, turns out the file was corrupt ..formatted hard drive , redownloaded the lame codec and dbpoweramp, now have mpeg layer 3 option and can convert ... but now the converted .wav has no sound?

Does your original file have sound? can you play it?

What settings does your original file have and what settings did you select for the conversion to compressed wav?

[sway]

Yes, original file has sound, and plays fine both from the cd and after copying it onto the pc.

original settings (what it says when you right click and the big yellow dbpoweramp box shows)
type - mp3 format sound
file ext - .mp3
length - 4:17
size- 6033KB
original size - 44345KB
compression - 7 to 1 (13%)
bitrate - 192
frequency - 44100
channels - 2 (joint stereo)
level - mpeg 1 layer III
encoded by - FHG- (guess)

converted settings = type - wave sound
file ext - .wav
length - 2:17
size- 941KB
original size - 8602KB
compression - 9 to 1 (10%)
bitrate - 192
format - lame mp3 (wave formatex header)
frequency - 32000
channels - 1

the settings on dboweramp i selected to convert was
compressed wave
format mpeg layer 3
attributes: 32000 Hz - 56kbps , CBR mono , 6KB/s

Hope ive gave you the right things!

OK, I think I may have found the problem. You are changing both the channels and the frequency at the same time. Things tend to break when you change more than one variable at a time. Try encoding your file to a normal, uncompressed WAV with settings of 44100Hz, 16-bit, 2 channels. Then do the same but with one channel. Then change the frequency to 32000Hz. Then convert to your compressed WAV.

If this works, then the problem was changing too many things at once. Try converting again but, say, convert to a 16-bit, 1 channel, 44.1KHZ WAV, then to the mp3-compressed, 1 channel, 32000Hz file.

Hope you followed this!

[sway]

Thank you LtData, that worked .... sort of. I done all that and got the file converted with sound , only it now plays high speed and distorted

[LtData]

OK, try keeping the frequency at 44100Hz. Why did you pick 32000Hz anyway? I ask this because most players, when the frequency is wrong, speed the file up and it sounds fast, as you described.

[sway]

Still playing at high speed , it's fine when i do uncompressed WAV with settings 44100Hz, 16-bit, 2 channels. Then do one channel, then change the frequency to 32000Hz. But as soon as i do compressed, it just goes high speed and distorted. the settings for compressed i choose are mpeg layer 3, 4100Hz , 64kbps, CBR mono , 7KB/s
I chose the 32000Hz settings cause im a music group that sends out .wav's to each other and thats the settings they all use, but none of them have a problem converting, so im doing something wrong somewhere lol
When im putting my file onto the pc, i use WMP and rip it at 192 kbps, could that be the problem? should i put it lower?
Sorry to be such a pain

[LtData]

Did you try a compressed-WAV with a frequency of 44100Hz?

Also, why compressed-WAV instead of normal mp3s? Do they just want compressed-WAVs?

[sway]

yes i done the 44100Hz compressed setting ... the settings for compressed i choose are mpeg layer 3, 44100Hz , 64kbps, CBR mono , 7KB/s

There to be compressed wav cause the files have to be smaller than 1kb

[LtData]

Did the 44100Hz compressed WAV also sound high-speed?

[ChristinaS]

yes i done the 44100Hz compressed setting ... the settings for compressed i choose are mpeg layer 3, 44100Hz , 64kbps, CBR mono , 7KB/s

There to be compressed wav cause the files have to be smaller than 1kb
That's not compressed enough. It's like mp3 at 64kbps - mono.
No way you'll get a 1Kb file that way.

You need to use lower settings - and this also includes a lower frequency (not that that make much differnce, but very low bitrate works better with a lower frequency as well).

Your problem is that you attempted to raise the frequency again - after having a standard wav at 32000KHz you went and tried to convert it to mpeg layer 3 at 44100KHz again.

[sway]

yes the 4100Hz compressed wav was high speed

ChritinaS sorry, bit of confusion ... when i done the 41000Hz compressed wav, i didnt convert to 3200Hz first , i done the uncompressed wav at 41000Hz then compressed wav at 41000Hz , it was before that when i done the 3200Hz.
I stopped trying for the 32000 after LtData's post, sorry for that

What is the point of using *.wav for this? Is it going to be used in some program that only supports *.wav? If it's just going to be listened to, then there is no point in not just using *.mp3

For using 56kbps 32khz mono, first convert your source file to 32khz 16bit mono. Any decent software player will not have any problem playing it back properly.

If its for playback in some kind of hardware player (I can't think of any that would only support mp3 compressed wave files and not *.mp3).. if it only support 44.1khz stereo, a mono file will playback at 2x the speed (or not at all), one sample to the left, one to the right, etc. etc.
