* This is an example for dumping things to a file. It demonstates, that

|
*
|
|
* a) you can use all aRts objects in a non-realtime environment (i.e.
|
|
* the time in the PlayObject will pass much faster than the outside
|
|
* time when dumping things to a file)
|
|
*
|
|
* b) complayObjectnents will be dynamically loaded as needed
|
|
*
|
|
* c) you need to do small tricks to get the signal flow going when you are
|
|
* not having audio modules around
|
|
*
|
|
* d) by implementing aRts modules, you can easily grab and insert data from/to
|
|
* arbitary non-aRts sources - for instance, a wave editor might implement
|
|
* own modules to get the wave from/to memory
