In theory, there's a lot. Not sure how probable some of them are.

CODE
[ec2-user@ip-10-226-89-162 cuetoolsnet-code]$ fgrep "new Exception" CUETools.Codecs.FLAKE/FlakeReader.cs
...
throw new Exception("invalid frame");
throw new Exception("unsupported bps coding");
throw new Exception("unsupported frame coding");
throw new Exception("invalid sample rate mode");

Thanks. "unsupported" is evidently not what metalheads want to use in a song title, so these were pretty quickly checked ;-)

Feature suggestion: CUETools could report e.g. "###DECODING ERROR### -" in front of the message.

Data on 320CBR vs LOSSLESS

As a genre, metal is fairly well represented on this forum, though maybe it's simply due to the personal tastes of the critical listeners submitting ABX logs. "Complex orchestral music," not so much. There are quite a few posts indicating that people tend to believe (that is to say in a predominantly religious sense) that classical music is somehow too good for lossy compression, though. To me it seems similar to the idea that high-end equipment is required and have a feeling that there is a huge overlap in the camps espousing these two.

Guruboolez has posted quite a few logs of classical pieces, though.

It seems the aotuv source were updated to vorbis 1.3.5.

Thanks for hinting me at this!

The new official aoTuV sources are identical to my aoTuV-1.3.5 patch except for one additional null pointer check in aoyumi's sources. I'll post updated Lancer patches soon.

Edit: Done! See first post.

No longer able to rip CDs with EAC

Hi Guys;

I tried this out, however the only effect I found was that iTunes complained.
EAC didn't work, still just locking up the ROM drive.

I tried restoring the registry, but iTunes still complains.
I'll probably need to reinstall it.

(it says:
The registry settings used by the iTunes drivers for importing and burning CDs and DVDs are missing.
This can happen as a result of installing other CD burning software.
Please reinstall iTunes.)


Other ideas?

Thanks,
Mark

Even if it is for Vista these filter drives cause trouble sometimes so you may check.

Laptop speaker - Clipping

I would like to know if it can have clipping when I put the volume of my laptop at max. I use the integrated speakers.
Generally speaking no. You should be able to run a 0dB normalized/maximized file at 100% without clipping your soundcard. (Your soundcard is generally "calibrated" for maximum output at the "digital maximum" of 0dBFS.) The exception would be if you're playing a floating-point file that goes over 0dB. (Not likely from Netflix or from any commercial release.)

QUOTE
I have to put my laptop volume to 100% to hear what people say. Is it dangerous ?
Clipping is distortion. It's only "dangerous" to the sound quality. wink.gif If it sounds bad when you turn it up, turn down the volume 'till you no longer hear distortion. Well... If you have a 100W amplifier you could fry your speakers if you drive your amp into clipping. But. the speakers built-into a laptop can handle anything the amplifier built-into the laptop can put-out.

QUOTE
For exemple, in Netflix, the volume is very low.
Laptops have tiny speakers and tiny amplifiers. wink.gif If you want to go louder and/or get better sound complete with bass, use external "powered" computer speakers, or plug-in headphones, or plug the laptop into your stereo system, etc.

I figured it out. It's a setting in the dsdiff decoder. You can pick the sample rate. When I cranked it up, it made a much larger file with a higher sample rate.


Could you tell me how to access that setting?

TIA

I know foobar2000 on wine sometimes has troubles to output a clean sound, at least on some hardware. For me, I have random dropouts during the playback, which is why I'm using deadbeef.
My other guess would have been the equalizer, on some music if you increase some bands, you end up clipping, so you have to adjust the EQ in a way that the highest band is at 0dB, and the unadjusted band is at -xdB

But since you're not using either, I don't know. Try using deadbeef maybe? It also has a built-in resampler plugin which you can play around with. It's also near-complete replacement for foobar2000 for most tasks.

No longer able to rip CDs with EAC

A System Restore is rarely possible after 6 weeks and it may not go well by making other things break, or not work at all.

Cut the time lost and grab the Windows installation disc and be mindful of how you install drivers in the future. Because some programs really do mess things up. EAC doesn't do that crap but other programs you're using might. This might be a little tedious and take a while, so patience is required.

A bug worth noting I found: EAC will crash on me if a disc has CD TEXT and there is a connection to the internet when I hit any button (IMAGE, WAV, CMP). I've found disconnecting from any network helps prevent crashes.

If you have Zone Alarm, use STOP ALL INTERNET ACTIVITY before starting a rip that has CD Text and RESUME ALL INTERNET ACTIVITY afterwards. (Windows 7 would ran like complete crap during this time)
Disable the Wi-Fi before ripping. Turn it back on when done. (I never used any computer that has Wi-Fi on it when using EAC... So I'm not sure if that works)
Remove the ethernet cord from the back of the computer before ripping. Plug it back in when done. (What I had to do when I upgraded to Windows 10 for the first month)

This part of the post is lightened up to avoid confusion.

Hi,

As a rule, the speakers in laptops are pretty egregious sounding. This is true even if some high end audio branding is involved.

However, most of the sonic badness in laptop sound has acoustical and electromechanical causes, and electrical amplifier clipping is generally a lesser influence.

IOW, the speakers may sound like there is clipping, but a detailed analysis would show that the speakers are being overdriven.

QUOTE

The actual power output of the amplifiers of the laptop are strongly influenced by the dynamic range of the music or drama recordings that you are playing. IOW, just because you have to crank the volume does not necessarily mean that power levels are high.

In the case of Netflix, their movies generally have far more dynamic range than say highly compressed music. So, you may have to crank the volume control to get adequate loudness most of the time. The actual power levels may only be high during infrequent action sequences in the movie.

Is it dangerous ?


Probably not.
