Reads and writes sound files.
Instead of trying to detach the Pd soundfiler code, which is very difficult to port over to C++ due to the number of dependencies, I chose to use STK's read and write methods. Since their classes are already written in C++ this saves a lot of time and really shouldn't sound any different.
This does not apply to table reading, such as tabwrite4~, which uses interpolation. When reading from arrays into the audio domain we will still use this method.
| double pd::SoundFiler::read | ( | std::string | file | ) |
Just like Pd's soundfiler, this class will read a file and store it in a vector which can be accessed using getArray(). Remember that the audio file data will be stored in RAM so large files can eat up lots of your applications' memory. If you want to read from disk look for readsf~, or the class ReadSF...in the future.
| void pd::SoundFiler::write | ( | std::string | fileName, |
| unsigned int | nChannels, | ||
| stk::FileWrite::FILE_TYPE | type, | ||
| Stk::StkFormat | format, | ||
| std::vector< double > | array | ||
| ) |
This method takes a filled array, and writes it to an audio format. This is similar to how Pd writes the contents of an array directly to a .wav. If you want to use buffered sound file writing look for writesf~ or the class WriteSF in the future...
