Using the alsa back end, when you specify the output device, Shairport Sync will now, by default, select the best output format and speed. For instance, if your output device is capable of 32-bit operation, it will be selected. In some situations, this will give a noticeable improvement in sound quality – see the discussion of audio improvements below. Audio Transient Reduction: A Disable Standby feature to eliminate certain faint-but-annoying audible pops and clicks has been added for alsa devices.The greatest bit depth will always be selected, and the lowest speed that is a multiple of 44,100. The setting prevents an output device entering standby mode and thus minimises standby/busy transitions, which can sometimes be heard. It is pretty impressive, especially combined with fixes to the dithering code described below. If you can enable 24- or 32-bit audio output to your output device, you can get even better results. This feature is available in the ALSA back end (standard in Linux) when it is driving output devices that can provide precision delay information, i.e. most hardware output devices and possibly some virtual devices. Basically, these are "deglitched" replacements for play start/play end program hooks. When a play session starts, the system goes active. When the play session ends, the system remains active for a period determined by the active_state_timeout setting, 10 seconds by default. If another play session starts before the period elapses, the system stays active otherwise the system goes inactive. The hooks are performed when the system goes active or inactive. #Swinsian inserts wrong album art code#.
