 **Audio** *source description.*  class **ost::AudioResample**\
 *The* **AudioResample** *class is used to manage linear intropolation buffering for rate conversions.*  class **ost::AudioTone**\
 *The* **AudioTone** *class is used to create a frame of audio encoded single or dualtones.*  class **ost::AudioBase**\
 **AudioBase** *base class for many other audio classes which stream data.*  class **ost::AudioBuffer**\
 *The* **AudioBuffer** *class is for mixing one-to-one soft joins.*  class **ost::AudioFile**\
 *A class used to manipulate audio data.*  class **ost::AudioStream**\
 **AudioStream** *accesses* **AudioFile** *base class content as fixed frames of streaming linear samples.*  class **ost::AudioCodec**\
 *The codec class is a virtual used for transcoding audio samples between linear frames (or other known format) and an encoded 'sample' buffer.*  class **ost::AudioDevice**\
 class **ost::TelTone**\
 *An object that is used to sequence and extract telephony tones based on a telephony tone descriptor retrieved from the parsed international telephony tone database.*  struct **ost::TelTone::\_tonedef**\
 struct **ost::TelTone::\_tonekey**\
 class **ost::DTMFTones**\
 **DTMFTones** *is used to generate a series of dtmf audio data from a 'telephone' number passed as an ASCII string.*  class **ost::MFTones**\
 **MFTones** *is used to generate a series of mf audio data from a 'telephone' number passed as an ASCII string.*  class **ost::DTMFDetect**\
 **DTMFDetect** *is used for detecting DTMF tones in a stream of audio.*
