| Constructor. | |
| virtual void | addNotifyAudioChange (AudioInfoSupport &bi) |
| Adds target to be notified about audio changes. | |
| virtual AudioInfo | audioInfo () override |
| provides the actual input AudioInfo | |
| virtual AudioInfo | audioInfoOut () |
| provides the actual output AudioInfo: this is usually the same as audioInfo() unless we use a transforming stream | |
| int | availableForWrite () override |
| bool | begin () override |
| (Re)start (e.g. if channels is set in constructor) | |
| bool | begin (AudioInfo info) override |
| Starts the processing with the defined number of channels. | |
| bool | begin (int channels) |
| Starts the processing with the defined number of channels. | |
| virtual void | clearNotifyAudioChange () |
| Deletes all change notify subscriptions. | |
