AudioThrottler & CircularBuffer

[jwallet]

No ideal either, it has difficulty to know when to cut when the user skip a track since Spotify immediately plays the other. So I will have to add a toggle feature on it. The feature can be useful if the user records a playlist and do not touch Spotify until the recording is done.

The user will probably have to turn off Automix and Crossfade features in Spotify Playback settings

may help resolve issue #170 (if spotify does not provide the track info, it won't do much)

AudioCircularBuffer keeps track of the current playback for about 10 seconds then overwrite itself

AudioThrottler sets the Buffer 5 seconds behind, it has 3 types of reader.
Once Spotify changes to the next track, TrimStart will be fired for the new recording, TrimEnd will be fired for the old recording, otherwise None will always be the default value.

• None (normal behavior), it gets the data from the throttler.
• TrimStart (use when starting a recording), it will set the reader to the next track (last detected silence)
• TrimEnd (use when ending a recording), it will ends as soon as a silence is detected.
