Function Documentation

nec_disable_denormals()

void nec_disable_denormals ( void )

inlinestatic

Disable IEEE 754 denormals on the current thread.

This is desirable for audio calculations as processing denormal values is significantly slower than normal values, and in the context of audio signal processing, denormal values are typically near silence and contain no useful information anyways.

Note

This only affects scalar calculations, as both x86 and ARM's SIMD operations always treat denormal values as zero.

nec_enable_denormals()

void nec_enable_denormals ( void )

inlinestatic

Enable IEEE 754 denormals on the current thread.

Note

This only affects scalar calculations, as both x86 and ARM's SIMD operations always treat denormal values as zero.
