The Advanced Linux Sound Architecture (ALSA) - utilities

Introduce a new keyword, "CombineArrays" to instantiate multiple nodes
of the type specified. For example:
CombineArrays.Object.Base.input_audio_format [
{
in_rate [
8000
16000
48000
]
in_bit_depth [
32
]
in_valid_bit_depth [
24
32
]
}
]
This would be expanded into 6 objects with the rate, bit_depth and
valid_bit_depth combinations of the arrays of values above.
Object.Base.input_audio_format [
{
in_rate 8000
in_bit_depth 32
in_valid_bit_depth 32
}
{
in_rate 16000
in_bit_depth 32
in_valid_bit_depth 32
}
{
in_rate 48000
in_bit_depth 32
in_valid_bit_depth 32
}
{
in_rate 8000
in_bit_depth 32
in_valid_bit_depth 24
}
{
in_rate 16000
in_bit_depth 32
in_valid_bit_depth 24
}
{
in_rate 48000
in_bit_depth 32
in_valid_bit_depth 24
}
]
The CombineArrays definition is an array so that multiple combinations can
be specified in order to deal with only valid combinations. For example,
16-bit bit_depth is only valid with 16-bit valid_bit_depth. So if we
also want to add those combinations with the multiple rates, the
definition would look like:
CombineArrays.Object.Base.input_audio_format [
{
in_rate [
8000
16000
48000
]
in_bit_depth [
32
]
in_valid_bit_depth [
24
32
]
}
{
in_rate [
8000
16000
48000
]
in_bit_depth [
16
]
in_valid_bit_depth [
16
]
}
]
