AAC / Re: TVBR vs CVBR
Last post by Anakunda -
I'm afraid there's not a listening test at that high bitrate and the results may not reproduce the results from 96k tests, so you'll have to make own ABX of both modes at this bitrate to be sure. But I bet you won't hear any difference as whatever mode at this bitrate is in the main transparent.

I meant the difference between 96kbps CVBR and TVBR that is aprox 96kbps, is almost negligible.

Ok thanks Kode54. In that case I'll just leave that DSP active as it solves the issue.

I fear that if I take it out (of the DSP chain) then it's likely to be so long before I even listen to another mono file again that by that time I will have forgotten the solution. ;)

But as mentioned before, I've tried .docx files with Microsoft Word, .rar files with WinRAR, .jpg images with XnView, .txt files with Emeditor and rename with Explorer, they can all edit when syncing. And on Foobar2000 side, not only when syncing files, but also after the syncing is complete the edit is not allowed (the file operation menu of Foobar2000 is only the exception).

It always has wanted exclusive access for writing (nothing should need to read the files while they're being written to.), and read-only sharing when reading the files. (nothing should be writing to the files while they're being read.)

I've just done some more testing and found something interesting. I does appear to be an issue that is specific to the audio hardware. I just plugged in a pair of Logitech USB headphones (and changed the foobar output device to suit) and the volume discrepancy is not apparent on this device.

In another test I used the Realtek control panel app to set the onboard audio to 6 channel and to configure to jack to "Mid/Sub" and sure enough the mono file is played through one channel (the other being the sub). In this configuration there is no audio present (on that center channel) when I play the stereo file. So it does appear to be doing what it's supposed to be doing re the 2 channel versus the 6 channel configuration. Just at reduced volume.

Anyway, using the "Convert mono to stereo" DSP in foobar solves the issue on the Realtek hardware, so I think I'll just leave it at that.

One final question though. Is there any performance penalty for leaving the "mono to stereo" DSP always active in the DSP chain? Will that just be ignored and do nothing when playing content which is already stereo (which is 99.999% of the time).

Thanks. :)

Curious about your audio setup. As I mentioned earlier there should be no difference on stereo equipment between real mono and mono mirrored to stereo. Certainly works that way with built-in Windows drivers.

Ok thanks Case.

- The audio setup is just an onboard "Realtek HD Audio" (ALC888 codec).

- The control panel app is configured for "2 Channel Speakers".

- The Jack is configured for "Headphones Out".

- Also tested with identical results when configured as "Line Out" (with ext headphones amp).

- The Foobar output device is  currently "DS: Primary Sound Driver".

- I have also used "DS: Realtek HD Audio Output" and "KS: Realtek HD Audio Output" and they both work the same as above.

- The estimated volume is about -12 dB for the mono file in each of the above cases.
