Detailed Description

This class extends dsdSampleReader providing acces to dsd samples and other info from dsf files.

Some of the rarer features of dsf are not well tested due to a lack of files: 8bit dsd

Constructor & Destructor Documentation

dsfFileReader::dsfFileReader ( char * filePath )

Class constructor.

filePath must be a valid dsf file location. If there is an issue reading or loading the file then isValid() will be false.

dsfFileReader::~dsfFileReader ( ) [virtual]

Class destructor.

Closes the file and frees the internal buffers.

void dsfFileReader::rewind ( ) [virtual]

Set the reader position back to the start of the DSD data.

Note that child classes implementing this method must call clearBuffer();

Reimplemented from DsdSampleReader.

bool dsfFileReader::step ( ) [virtual]

Step the reader forward by 8 DSD samples.

This causes the next 8 DSD samples to be added into the front of the circular buffers (one uint8).

Reimplemented from DsdSampleReader.
