 audio streams, and data format and sample rate conversion.
 .SS "Overview"

 The audio framework provides a software mixing engine (audio mixer) for all
 audio devices, allowing more than one process to play or record audio at the
 same time.
 .SS "Multi-Stream Codecs"

-.LP
 The audio mixer supports multi-stream Codecs. These devices have DSP engines
 that provide  sample rate conversion, hardware mixing, and other features. The
 use of such hardware features is opaque to applications.

 It is not possible to disable the mixing function. Applications must not assume
 that they have exclusive access to the audio device.

 Digital audio data represents a quantized approximation of an analog audio
 signal waveform. In the simplest case, these quantized numbers represent the
 amplitude of the input waveform at particular sampling intervals. To achieve
 the best approximation of an input signal, the highest possible sampling
 frequency and precision should be used. However, increased accuracy comes at a

 addition to the formats that the audio device supports directly, other formats

+Sample rate conversion can be a compute-intensive operation, depending on the
 number of channels and a device's sample rate. For example, an 8KHz signal can
 be easily converted to 48KHz, requiring a low cost up sampling by 6. However,
 converting from 44.1KHz to 48KHz is computer intensive because it must be up
 sampled by 160 and then down sampled by 147. This is only done using integer
 multipliers.

 All modern audio devices run at 48 kHz or a multiple thereof, hence just using
 48 kHz can be a reasonable compromise if the application is not prepared to
 select higher sample rates.
 .SS "Encodings"
-.sp
-.LP
 An encoding parameter specifies the audiodata representation. u-Law encoding
 corresponds to CCITT G.711, and is the standard for voice data used by
 telephone companies in the United States, Canada, and Japan. A-Law encoding is
 also part of CCITT G.711 and is the standard encoding for telephony elsewhere
 in the world. A-Law and u-Law audio data are sampled at a rate of 8000 samples

 Linear Pulse Code Modulation (PCM) is an uncompressed, signed audio format in
 which sample values are directly proportional to audio signal voltages. Each
 sample is a 2's complement number that represents a positive or negative
 amplitude.
 .SS "Precision"
-.sp
-.LP
 Precision indicates the number of bits used to store each audio sample. For
 instance, u-Law and A-Law data are stored with 8-bit precision. PCM data can be
 stored at various precisions, though 16-bit is the most common.
 .SS "Channels"
-.sp
-.LP
 Multiple channels of audio can be interleaved at sample boundaries. A sample
 frame consists of a single sample from each active channel. For example, a
 sample frame of stereo 16-bit PCM data consists of 2 16-bit samples,
 corresponding to the left and right channel data. The audio mixer sets the
 hardware to the maximum number of channels supported. If a mono signal is
 played or recorded, it is mixed on the first two (usually the left and right)
 channel only. Silence is mixed on the remaining channels.

 The mixer discards the low order 8 bits of 32-bit Signed Linear PCM in order to
 perform mixing. (This is done to allow for possible overflows to fit into
 32-bits when mixing multiple streams together.) Hence, the maximum effective
 precision is 24-bits.
