Add reverb effect on playing sound

[nakane11]

Dependency

pip install pedalboard
pedalboard can work on Python 3.6 or above.

Sample

• window 1
  $ roslaunch soundplay_node.launch

• window 2 (Invoke python)

 import rospy
 from sound_play.libsoundplay import SoundClient
 
 rospy.init_node('soundclient_example')
 soundhandle = SoundClient(blocking=True)
 soundhandle.say('Say-ing stuff while block-ing')
 soundhandle.say('Say-ing stuff while block-ing', reverb=0.5)
 soundhandle.say('Say-ing stuff while block-ing', reverb=0.9)

I confirmed the sample, but haven't written the dependency yet.
