MAS Player Amiga AMP/AMPlifier MP3 Mixing ????

[platon42]

It's technically not possible to generate gapless MP3s. There's always at least an empty frame at the beginning and the padding (to a full frame) at the end. There is an extension tag (lame generates this, if you want it to) for some software players to tell them about the real start and end of the sound to allow gapless playback.

However, with normal MAS hardware, you won't be able to avoid this gap completely, but you can make it as small as about 20ms -- but the player (AMPlifier) has to continue sending data right after the other track ended -- which it doesn't (no prebuffering for the next song).

And no, with the Hardware decoder, no mixing is possible. It just takes the unmodified mpeg stream.

The cross fader needs access to the sample data the decoder generates out of the MP3 stream. This is not possible with the MAS Player (no audio data feedback, but directly coupled with the CS D/A converter), hence the cross fader plugin won't work.

The CD32 FMV card (BTW: That's where the mpeg.device standard comes from) can only decode MPEG 1/2 Layer 2, but not Layer 3 (which is normally abbreviated as MP3).

@leirbag28:

At the time the CD32 FMV was developed, there was no MPEG 1/2 Layer 3 (or at least it was not popular at that time (1993?). The FMV unit was designed to play back video CDs, which used MPEG1 streams (and this included only MPEG Layer 2). Layer 2 can be encoded much quicker, but needs a higher bitrate for the same quality as Layer 3.

And about MP3s: it really depends on your settings (and the encoder used), you can encode MP3 with 256 kbit/s that sound like crap -- and at the same time generate (VBR) MP3s with <100 kbit/s that sound very close to the original.
(And yes, I think of doing a good encoding job as a kind of art, and most of the stuff you get from the internet is crap, broken, bad quality, truncated, no ID tags or spelling mistakes, so I do the encoding from original CDs myself ).

BTW: Somebody want a LAME3.97beta binary for MorphOS?

MASPlay ?

Not sure what you mean exactly...

or something like that.

Not with the command I provide with the masmpeg.device (only supports the PRO version).

Commandline? I usually use Frogger AD MELODY, but I suppose it works just the same with AD MAS.

Anyway, I suggest to RTFM (ReadTheFineManual)
