wave

Play back audio data

Syntax:

wave [-derstvwx] [-a [card_num:]dev_num] [-b num_frags]
     [-c hw_channel_bitmask[,hw_channel_bitmask...]] [-f frag_size]
     [-m mixer_name] [-n num_frags] [-o audio_type] [-p volume]
     [-R value]

Runs on:

QNX Neutrino

Options:

-a [card_num:]dev_num

The card and device number to play out on.

-b num_frags

(QNX Neutrino 6.6 or later) The number of fragments while buffering.

-c hw_channel_bitmask[,hw_channel_bitmask...]

Voice matrix configuration. The first argument is the hardware channel bitmask for application voice 1, the second is that for application voice 2, and so on, up to eight voices.

-d

(Audio for AMP 2.0 or later) Continuously repeat the input file.

-e

(QNX Neutrino 6.6 or later) The content would like to be played on a secure channel.

-f frag_size

The requested fragment size.

-m mixer_name

The string name for mixer input.

-n num_frags

The requested number of fragments.

-o audio_type

(QNX Neutrino 6.6 or later) The name of the audio type registers with audioman.

-p volume

The volume, as a percentage.

-R value

(QNX Neutrino 6.6 or later) The SRC rate method; value must be one of the following:

1 — 7-point Kaiser windowed
2 — 20-point remez
3 — linear interpolation

-r

(QNX Neutrino 6.6 or later) The content can be played only on a secure channel.

-s

(QNX Neutrino 6.6 or later) The content is protected.

-t

(QNX Neutrino 6.6 or later) Display timing information, in nanoseconds, of when the data is sent.

-v

Be verbose.

-w

(QNX Neutrino 6.6 or later) Use separate threads to control and write audio data.

-x

(QNX Neutrino 6.6 or later) Use the mmap() interface.
