The idea was more about the network-stream or the audio-stream or the keyboard-input-stream... When outputting audio, you'd want an echo effect, I'd like the code to be something like:
Code: Select all
stream::effect<audio> echo = system::getStreamEffect("audio:44100/6/16", "echo");
module <file, audio> mp3loader = system::getModule("file:mp3", "audio:44100/6/16");
module <audio, pausablestream> audiostreamer = system::getModule("audio:44100/6/16", "??? - something like a pausable audio stream");
stream audio = audiostreamer(mp3loader(new file("/mp3z/track01.mp3")));
stream echoedaudio = echo(audio);
module <audio, sound> play = system::getModule("audio:44100/6/16", "sound");
play(audio);
but as you can see this is far from nice, and I even had to leave a gap because I can't think of a way to do that

hmm. So actually you have
Code: Select all
<filter family="audio" name="echo">
<input allow="audio/raw">
<encoding freq="system.audio.known-freq.*"/>
</input>
<output produce="audio/raw"><norecode/></output>
</filter>
<filter family="audio" name="codec">
<input allow="audio/mp3"/>
<output produce="audio/raw">
<encoding freq="system.audio.known-freq.*"/>
</output>
</filter>
coming with the "echo" and "MP3decoder" modules ...
I'd then say that you create a 'direct' playback with
Code: Select all
Speakers=System.locate(family="audio", name="output");
Codec=System.locate(family="audio", name="codec",
input=myFile.getAudioDescriptor(),
output=Speakers.getAudioDescriptor());
Codec.setInput(myFile); // connects myFile --> codec
Speakers.setInput(Codec); // connects codec --> speakers
And if you want to add an echo module
Code: Select all
Speakers=System.locate(family="audio", name="output");
Source = Speakers.getInput();
Echo = System.locate(family="audio", name="echo",
input=Source.getAudioDescriptor(),
output=Speakers.getAudioDescriptor());
Echo.setArg(parameter="delay", value="0.05ms");
Echo.setInput(Source); // disconnects codec -- speakers and
// replace with codec -- echo
Speakers.setInput(Echo);
nice enough ?
