Subject: Re: play WAV?
From: Joris van den Heuvel (joris.bass_at_planet.nl)
Date: 2003-09-03


Ah, you are joking. Now I get it. And while you're at it, you're trying to
get a rise out of this, to insult Daniel and Linus, and let them take the
blame for you doing so. Smart.

> anal retentive

You mean asshole? (No, please, take no offense, as you don't want us to take
any offense from your posts)

Man, do YOU have an attitude problem!

I used to be like you, you know. Wouldn't/couldn't take no for an answer and
hard-headed as hell. Back in the days when I was 4.

| That is a shame ...but only a limitation, not a show-stopper.
| Do you know what the datarate limit is?
|
| It will be nice to use the digital I/O as a serial port to allow the
| control of external devices - LCD -> PAL/NTSC display converter anyone?
|
| >>MOD ...What is so difficult? - I used to play MODs on my old 286!

|
| Pretty much what I was thinking - I like the idea of using my recorder as
a
| composer - something to do whilst sitting on the train - for composition I
| could use low bitrate samples (although strict MOD actually specifies
8KHz,
| 8bit samples) and then use higher quality samples for the final mix-down
| (on my PC).
|
| >>MIDI ...just like MOD with preset sample bank
| >See above.
|
| I do fully appreciate that there are and will be virtually insurmountable
| problems - well, without SOME level of hardware mod - which is way beyond
| _me_. But I can also appreciate how much more CAN be done - I've just
| never been a settle-for-second-best kind of guy. Single parent family,
| anal retentive, you know the social stereo-type ;)
|
| I suppose what I am trying to say is, Thanks for your support.
|
| >>The reason "we don't have enough OGG support provided by hardware" is
| >>because we do not have the MAS SDK and therefore cannot use 50% of the
| >>hardware - LOL
| >In the MAS case, the problem will not necessarily be CPU power, but
rather
| >(lack of) memory. The MAS has 4 or 8k of memory for both program and
data.
| >For example, the Tremor OGG decoder has hundreds of kilobytes of lookup
tables.
|
| First off, I am very happy to use this subject for little more than
| acedemic value.
| I never have or had or plan to have any plans to even glimpse at the OGG
| code - simply no personal interest.
| But academically, it really depends on how well we can get the two
| processors to talk to each other and precisely what has been implemented
in
| the MAS instruction set. There is no reason at all to exclude complex
| functions such as SIN or COS, as they will already be featured on the
| silicon elsewhere - but without more info, it's ALL guesswork at this
level.
