alsa-project/alsa-utils pull request #127 was opened from ranj063:
With the addition of the math expression evaluator in alsa-lib, we can use it to evaluate simple math expresionns for objects attribute values based on other attributes.
For example to calculate the size attribute in buffer objects:
size "$[$[$[$periods * $sample_size] * $channels] * $[$[$rate * $period]]] / 1000000"
The size attribute value will be computed from the values for the periods, sample_size, channels, rate and period attribute values set in the buffer object.

With the addition of the math expression evaluator in alsa-lib, we can use it to evaluate simple math expresionns for objects attribute values based on other attributes.
For ex: we can set the expression for buffer size as follows:
buffer_size "$[($in_channels * 48) * 4]"
The buffer_size attribute value will be computed with the attribute value "in_channels" based on the expression above. So if $in_channels = 2, buffer_size will be evaluated to 384.
