Gosh.

Lately I've just been refusing to master anything obnoxiously loud.

Good thing I pay my mortgage by writing Audio Unit plugins that are expected to sound GOOD  

Nothing _I've_ mastered in the last half a year would cause problems with clipping mp3s. ...or would help pay much of my mortgage...

Enjoy. I'm just glad to be out of it. Such a relief to refuse to care any longer about meeting or beating the horribleness...

hey chris,   haven't tried your plug-ins. how quiet are they?!

Totally silent. Except for the dither plugin, that adds noise

So looking at these results LAME and iTunes 192 (without filtering) work best?

I generally export from Sequoia at 192kbps for clients. As long as there isn't intersample clips and the level is -0.3dBFS I haven't had a problem with clipping.

[cerberus]

the codecs all sound different; whereas the experiment only depicts the gross effect on
peak amplitude values.  i wouldn't recommend using such limited data as a primary
criterion for determining suitability. in this case, i only made a measurement for
the sake of [going back to make] a gain adjustment before src and dithering.

Is there any MP3 coding scheme out there that lets the ME listen to the coding in real time?

I don't know if it would affect my EQ decisions or not, but I always listen through the final dithering of choice? Why not be able to turn on the MP3 compression to hear what's going to happen when it hits the meat grinder?

There are many mp3 (and other lossy codecs) flavours available, so it won't be easy to predict how consumers will hear your sound (similar to different speaker models and setups).
If you're concerned about (low bitrate) lossy codec compatiblity of your audio, the following white paper might be of interest.
I found it quite informative.

If you are using RX on a mac, it will decode MP3 to floating-point PCM, and you can get the non-clipped decoding, suitable for normalization or limiting. This doesn't work on a PC yet! (the Windows WMA decoder that we are currently using for MP3 can only decode to fixed-point).

What about Foobar for Windows? I was told it would decode in 32 floating point.

thanks kees. in one sense: mp3 turns out  just like vinyl. one is never going to get
away with a big fat  -stereo- bass or kick drum. i have used mp3 to try and prove
to clients that such things do not work. the problem may arise that a mix
engineer prefers to claim  mp3 sucks; and so does not recognize that
their mix is deeply flawed.

I just got myself a new laptop (HP dv9686) for home use and just for fun I ripped a self-produced CD into mp3 directly with the windows media player.

The OS is Vista Home Premium and I don't know if digital audio in Windows has become better, but the reults were excellent at 192 kbps.

I might add that the CD is peaking around -6 dBFS (classic chamber music). And I must add that I am no fan of mp3 at all.

But I felt the reults were extremely "good". Ripping this way. I felt absolutely no urge what so ever to rip or encode with something else. Windows Media Player. WTF? Well...

This kinda reminded me that getting softer will save people a lot of time trying to find all kinds of codecs and solutions for everything. Time that can be spent on better things in life.

Due to the way mp3 encoding works, it seems sometimes rock and pop is the worst case scenario whereas classical music doesn't take the penalty nearly as much.
