This limits the maximum gain we perform in software to approximately 20 dB. There does not appear to be a good reason for greater gain, and clipping to 20 dB can prevent accidentally setting an absurdly large volume and potential damage to the ears. --- src/pulse/volume.h | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/src/pulse/volume.h b/src/pulse/volume.h index 35128b6..d646a7b 100644 --- a/src/pulse/volume.h +++ b/src/pulse/volume.h @@ -113,7 +113,8 @@ typedef uint32_t pa_volume_t; #define PA_VOLUME_MUTED ((pa_volume_t) 0U) /** Maximum valid volume we can store. \since 0.9.15 */ -#define PA_VOLUME_MAX ((pa_volume_t) UINT32_MAX/2) +/* This value corresponds to ~20 dB (of software amplification) */ +#define PA_VOLUME_MAX ((pa_volume_t) 141193) /** Special 'invalid' volume. \since 0.9.16 */ #define PA_VOLUME_INVALID ((pa_volume_t) UINT32_MAX) -- 1.7.3.2
