I need some help

@ vpnmaster

Please, do not use JPEG format for such waveform pics.
For this purpose JPEGs are the wrong choice.
Use PNG instead !
It creates much smaller files (for pictures with limited colours) and most important the PNGs will be lossless !

JPEG format is only recommended for pictures (or screenshots) of very complex picture content such as real camera shots (humans, animals, sceneries, buildings, etc.) with millions (or thousands) of colours.
But for schematic pictures (with limited colours) like program window content PNG is the standard format.

So, please next time use PNG (or if you still have the original BMPs, please replace the JPEGs here with new PNGs) !

If you are not sure how complex a screenshot is (how many colours it has),
you can do the following:
1. Try PNG format and see how big the resulting file would be as PNG file.
2. Try JPEG (but please with higher compression ratio as you did here)
and see how big the resulting file would be as JPEG file.

Not needed. I can tell in half a second that RadioDJ is processing the audio. A lot. That’s the problem. You need to figure out how to turn off ALL audio processing that RadioDJ is doing.

RadioDJ is still processing the audio, absolutely.
Here’s the difference between the two…

The green that’s left is what RadioDJ is doing.
Notice how it’s almost completely symmetrical too.
Definitely some pretty heavy dynamics processing still
going on there.

I did some research, and apparently there’s an "mp3 free" version of it that just uses the OS’s default mp3 decoder, and there’s the normal version of bass that uses mpg123.

You might try the two different versions, and see if that makes a difference. The full BASS version with mpg123 should be the one you wanna use. But try both.

Latest version download:

the normal bass.dll in the main directory, and the "mp3 free" version in that directory of the zip of the same name. 🙂

[quote author=”radioDJ”]After i revised the code for the processing FX i’ve got these results. In red is the original file and in black is the recorded output from RadioDJ thru the onboard card, so the quality may have suffered, but it was my only option because my main card has processing unit built-in so it would modify the sound.[/quote]
Hi, nice to meet you. 🙂

If you install the Breakaway Live demo, it will also install a licensed version of Virtual Audio Cable… virtual soundcards with no processing that are completely digital, so you should be able to get a much more transparent comparison. Then you just set your software to output to one of the cables/pipelines, and record from it with whatever recording software you’re using.

[quote author=”radioDJ”]the two waveforms seem almost identical.[/quote]Is this the way it should look like, Jesse ?

Maybe I am wrong (?):
The waveforms cannot look 100 % identical due to the principle of kernel streaming (mixing) !?
I remember my own tests approx. two years ago when I have done a comparison between VAC, Total Recorder Kernel-mode virtual device driver (KS) and the (old) User-mode virtual device driver.
Only recordings from User-mode virtual device driver gave me exact (bit true)
copies of the sources (16 Bit, 44,1 kHz WAV).

Very important:
Obvious most people here (and in other audio related forums) prefer using Cool Edit based audio editors (-> old Cool Edit Pro 2.x or Adobe Audition 1.5, etc.).
You can open with these editors an audio file hundred times (using clones of the same source file) and you will get hundred different waveform drawings !
Very small differences indeed (but there is always some kind of random interpolation).
That’s why I have used Wavelab 5 for quick waveform comparisons, after I had discovered this problem in Audition 1.5.

So, I don’t know if this random waveform drawing appears with other audio editors, too. (@ radioDJ what audio editor do you use ?)
➡ clone an audio file and open these with your (Cool Edit based or others) audio editor, then you see the difference.

PS: Forget about my PNG advice (if you do not need an exact lossless representation).
Generally it is correct (for schematic window content), but for hi-res waveforms (even with two colours) you can create smaller files with JPEG compression.
If you need an exact pixel by pixel (lossless) file PNG is still the better choice (though the file size is bigger as with JPEG @ 1:5 or 1:10 compression ratio) !

@ radioDJ

So, have you done an update build ?
