wrong bit rate and sampling for mp3 x64

[flagpole]

using these settings:

ie asking for 96kbps j-stereo abr lame sampled same as input 48hHz

i get the output as indicated here

ie 128kbps sampled at 32kHz

whatever settings i use there is something wrong

i can see that the correct command line is being passed to lame64.exe ie

Code: Select all

--abr 96 -m j -q 2 --noreplaygain --add-id3v2 -r -s 48000 --quiet - "C:\Users\Nigel\AppData\Local\Temp\mctemp3380.mp3

i realise it's abr and the bit rate can't be exact but it is exactly wrong

i'm at a complete loss to explain it.

thanks for looking at it.

i've had problems for months. do you know where i can get the older versions from? 32 or 64?

and how do you show the advanced options?

another smaller bug - if you use the time tab to select a portion of the source file to encode, the summary tab doesn't reflect this. should be a fairly easy fix.

[flagpole]

i can confirm that this bug is only present for .avi format. not for .mp4 muxed by mp4box

[flagpole]

yeah ok. it does it with a plain mp3 file.

i should more accurately have described it as not having been present one time i used it with mp4box

[flagpole]

i've gone back to 0.7.2.4524 32bit (had to slip in an ffmpeg i found lying about as the installer nolonger downloads it)

and all is well

[flagpole]

can i just ask a question about the bug reporting and fixing procedure here.

is it possible for me to know if this is sort of logged as a bug with a view to fixing it? is that how it works here? or is it sort of whatever they want to fix?

just that for me this bug is HUGE.

LAME will automatically do down-sampling when specified bitrate is low. A workaround is to add --resample $(SampleRate) in LAME's extra options.

[flagpole]

thanks for the reply....

I have a couple of questions.

when i add --resample $(SampleRate) to the lame extra options, it's added to the command line as
"--resample $(SampleRate)"
where as i think it needs to be:
--resample "$(SampleRate)"

could this maybe be added by default, there is a sampling dialogue in the lame tab and currently it's not doing what it suggests.

i'm still a bit confused too. i often encode at abr 128, and this invariably comes out at 192kbps where as trusty old version 0.7.2.4524 (32bit) with lame 3.98.2 gives an output pretty close to 128 with exactly the same settings.
