License & Copyright +---------------------- + +This Package is available "as is" under MIT License. Unless stated otherwise, +the copyright is held by Gustavo A. Hoffmann. + +2. Supported Platforms +---------------------- + +This Package has been tested on the following compilers / platforms: + +- GNAT GPL 2015 for Linux + +The Package is expected to work on Windows and Mac platforms. + +3. Features +----------- + +### Wavefile Features + +Reading and writing of wavefiles supporting following features: + +- Stereo and multichannel audio +- Audio samples with following bit depths: + - 16-bit PCM + - 24-bit PCM + - 32-bit PCM +- Wave-Format-Extensible (WAVEFORMATEXTENSIBLE) +- Conversion between PCM buffer data type and wavefile data type. + - Adaptations for different precisions are performed automatically. + +### PCM Buffer Features + +- Built-in handling of PCM buffers + - The Wavefiles Package is a generic package that can be instantiated for + different formats of PCM buffers. + - When instantiating the generic package, the user must specify: + - The maximum number of samples that the buffer can contain + - The numerical data type for storing the PCM samples + - The numerical data type of the PCM samples can be: + - A floating-point type of arbitrary precision + - A fixed-point type of arbitrary precision + - When declaring an instance of the PCM buffer, the user must specify: + - The number of channels + +- Support for operations on PCM buffers: + - "=", "*", "+", "-" + - Custom operations (using function Wavefiles.PCM_Buffers.Perform) + +4. Known Issues and Limitations +------------------------------- + +### Wavefile Features + +Following features are not currently supported: + +- Reading and writing of 8-bit PCM wavefiles +- Reading and writing of wavefiles in floating-point format + +### PCM Buffer Features + +- Data type conversion to be investigated and improved. + - Conversion of small negative values might be improved. + +### Documentation + +- Extensive documentation and tutorials are missing. + - Please refer to the test folder for an example on how to use the Package. + +### Testing + +- Unit test for the Package is missing. + - Just a test module for manual checks is currently available. + +- Testing of wavefiles in various formats is missing. +- Testing of erroneous wavefiles is missing.
