Usage: `--format {F32|S16}`. Default is F32.
- Implemented for all backends, except for JACK audio which itself
only supports 32-bit output at this time. Setting JACK audio to S16
will panic and instruct the user to set output to F32.
- The F32 default works fine for Rodio on macOS, but not on Raspian 10
with Alsa as host. Therefore users on Linux systems are warned to set
output to S16 in case of garbled sound with Rodio. This seems an issue
with cpal incorrectly detecting the output stream format.
- While at it, DRY up lots of code in the backends and by that virtue,
also enable OggData passthrough on the subprocess backend.
- I tested Rodio, ALSA, pipe and subprocess quite a bit, and call on
others to join in and test the other backends.
- Store and output samples as 32-bit floats instead of 16-bit integers.
This provides 24-25 bits of transparency, allowing for 42-48 dB of
headroom to do volume control and normalisation without throwing
away bits or dropping dynamic range below 96 dB CD quality.
- Perform volume control and normalisation in 64-bit arithmetic.
- Add a dynamic limiter with configurable threshold, attack time,
release or decay time, and steepness for the sigmoid transfer
function. This mimics the native Spotify limiter, offering greater
dynamic range than the old limiter, that just reduced overall gain
to prevent clipping.
- Make the configurable threshold also apply to the old limiter, which
is still available.
Resolves: librespot-org/librespot#608
* Remove default impl for `SessionConfig`
* Move util mod to single file
* Restore privacy of mods
* Move `fn get_credentials` to application
* Remove `extern crate` statements
The locations of credentials, volume and audio are now stored
in three separate Optional<PathBuf>s.
Removed the clearing of the cache if an error occurs. This might
be added again later.
Refactored the old `--linear-volume` flag to a more generic `--volume-ctrl` flag that takes the options of `[linear, log, fixed]`. It defaults as previously to log.
* Enable gapless playback via runtime flag
* Set gapless playback as default, use `--disable-gapless` to turn it off
* Ensure sink restarts b/w tracks when gapless is disabled
Since port 80 is the default port for the HTTP protocol, `url.port()` returns `None`, causing an "invalid proxy" message. Using `port_or_known_default()` will only return `None` if the both the port has been omitted and an unknown protocol has been specified.
Ensure the player events are emitted correctly.
Only call the external script on events we want to notify about.
Stop sink when loading to pause.
cargo fmt
- change communication between player and spirc to use player events channel.
- enhance player events channel
- have spirc send loading messages to Spotify
- enable preloading of tracks in the player
* create Volume struct for use with Cache
* add "volume" file to Cache
* load cached volume on start, intial overrides cached overrides default
* amend volume_to_mixer function to cache the volume on every change
* pass cache to Spirc and SpircTask so volume_to_mixer has access
* rustfmt changes
* revert volume_to_mixer function and Spirc/SpircTask cache variable
* Volume implements Copy, pass by value instead of reference
* clamp volume to 100 if cached value exceeds limit
* convert Volume to u16 internally, use float and round to convert hex->dec
* convert initial_volume and ConnectConfig.volume to u16 as well
* add cache_volume function to SpircTask
* remove conversion to/from percentage on cached volume
* consolidate device.set_volume, mixer.set_volume, and caching
* streamline intial volume logic
