* Discussion: copying .gig samples is a bit tricky. It requires three |
461 |
|
* steps: |
462 |
|
* 1. Copy sample's meta informations (done by CopyAssignMeta()) including |
463 |
|
* its new sample waveform data size. |
464 |
|
* 2. Saving the file (done by File::Save()) so that it gains correct size |
465 |
|
* and layout for writing the actual wave form data directly to disc |
466 |
|
* in next step. |
467 |
|
* 3. Copy the waveform data with disk streaming (done by CopyAssignWave()). |
