Change kpbs in wav audio

[oligophant]

It is possible change a

192 kBit/s,48000Hz,Stereo, 16bits per sample

to a

128 kBit/s,48000Hz,Stereo, 16bits per sample

i want to drecrease the size file from 34mb to 20mb, how could i do that, i tried in Vegas 8.0 with wav(microsoft) but the olny options it gave me is 56kbps 24000Hz,stereo ,16bits

any ideas, thanks in advance :D

changing kbps in wave can be achieved in two ways:
1) lowering sampling rate (cutting out higher frequencies), or 2) lowering sample resolution (increasing quantisation noise).
Wave PCM is not lossy compression format.
Maybe you are talkin about some sort of compressed wave?
=============================================

On the other hand 192 kbps for PCM 48000 Hz, 126 bit stereo waveis simply impossible.
Because the kilo-bits-per-second calculation:
(48000 * 16 * 2)/1000

@oligophant 192 kBit/s,48000Hz,Stereo, 16bits per sample to a 128 kBit/s,48000Hz,Stereo, 16bits per sampleWhat is the format of the audiostream (e.g. .MP3, .WAV, .MP2, .AC3, .AAC)?

It is just a wave made by virtualdub from an avi video

Sampling rate: 48000Hz
Channels: 2 (stereo)
compression: Fraunhofer IIS MPEG Layer-3 Codec
layout: 1484 chunks (0.50s preload)
length: 61873 samples (24:44:95)
min/avg/max/total frame size: 12096/24015/24192 (34804k)
Data rate: 192kbps (0.10% overhead)

and when i extract it (direct stream way) Vega show me this properties

File type: Wave
auido format: Lame MP3
audio attributes: 48000Hz, 16bit, Stereo

its a wave file.

i want to make the wave like this

sampling rate 48000hz
channels: 2(stereo)
compression: Fraunhofer IIS MPEG Layer-3 Codec
layout: 34881 chunks (0.50s preload)
length: 23284224 samples (24:15:26)
min/avg/max/total frame size: 281/667/8000 (22739k)
data rate: 128kbps (3.47%overhead)

someone already do that, so what im asking, is how he did that?.

No, it's not a WAVE file, it's an .MP3 (compressed) file.i tried in Vegas 8.0 with wav(microsoft) but the olny options it gave me is 56kbps 24000Hz,stereo ,16bitsThat's because it's limited by the .MP3 code you have installed - and it's apparent that you only have the Microsoft Windows default .MP3 codec installed (This makes it apparent that you didn't create the .AVI from which the audiotrack was extracted)...
