Currently, the source implements playback in pure C on all platforms except ARM, where a [currently] small amount of assembly (see asm_arm.h) is used to implement 64 bit math operations and fast LSP computation. If building on ARM without the benefit of GNU build system tools, be sure that 'ARM_ASSEM' is #defined by the build system if this assembly is desired, else the resulting library will use whatever 64 bit math builtins the compiler implements.
No math library is required by this source. No floating point operations are used at any point in either setup or decode. This decoder library will properly decode any past, current or future Vorbis I file or stream.
Further information can be found in the original README.
This decoder is dependend on LibOgg, which is part of arduino-libopus
You can download the library as zip and call include Library -> zip library. Or you can git clone this project into the Arduino libraries folder e.g. with
cd ~/Documents/Arduino/libraries
git clone https://github.com/pschatzmann/arduino-libvorbis-tremor.git
git clone https://github.com/pschatzmann/arduino-arduino-libopus.git
I recommend to use git because you can easily update to the latest version just by executing the git pull command in the project folder.
Detailed Tremor API Documentation can be found at doc/index.html
I recommend to use this library together with my Arduino Audio Tools. This is just one of many codecs that I have collected so far: Further details can be found in the Encoding and Decoding Wiki of the Audio Tools.
