Sorry for the delayed reply.

I wanted to reply on Monday, but I had problems to get access to the
computer.

lame is required by swfc to embed .wav files in mp3 format.

If lame isn’t  present at compilation time, swfc will embed .wav files
in wav format. In other case, sound embedding will be in mp3 format.

It was my fault: not accurate explaination.

Precompiled binaries (Windows or Linux) don’t have this option. The
dependency has to be corrected and the binaries must be generated again.

BTW, the bug is real. I guess it should be fixed.

I want to experiment. I promise nothing will be destroyed ;-).

Again, I’m experimenting. I have compressed the sound I don’t notice any
significant difference from 16MHz to 8MHz.

But I would like to have a sample that I can share with others, so they
can test and comment.

Many thanks for the wav2swf tip. I will experiment with this.

But if this works, having the ability to reduce one step and directly
handle it through swfc without prior conversion would make things esier.

But my previous attempt was successful to some extent. (I may agree with
you that this is a dangerous reward to my stubbornness ;-).)

I forgot to mention that Gnash developer Sandro Santilli fixed an issue
I opened the very first day I pointed to it.

There are another issues, but creating automated testcases for Gnash
(https://savannah.gnu.org/bugs/?40459) is something I have to learn
first ;-).

Many thanks for your help,


Pablo
