About

This skill plays a sound in the given note or an sound in the given guitar string. This can be used to tune a musical instruments.

Mycroft is using the even tempered (aka equal tempered) scale, where an octave is a frequency ratio of exactly two and a semitone is a frequency ratio of exactly the twelfth root of two. In the real world however many different temperaments may be used - see en.wikipedia.org/wiki/Musical_temperament - and octaves too can vary in size, see en.wikipedia.org/wiki/Stretched_octave.

Also Mycroft call middle C for "C4" : this is the commonest octave numbering but some people call middle C for "C3" or even for "C5".

Examples

• "Gime me an C note"
• "Give me an guitar Low E string"
• "Give me an A4 note"
• "Give me an violin A string"

Mycroft knows the strings on these instruments:

• guitar
• mandolin
• cello
• viola
• banjo
• bass

sound-tuner-skill's Issues

Problems on Mark 1

"Give me an A4" results in

  File "/opt/mycroft/skills/sound-tuner-skill.andlo/__init__.py", line 38, in handle_tuner_sound
  File "/opt/mycroft/skills/sound-tuner-skill.andlo/__init__.py", line 60, in make_sound
  wavef = wave.open('sound.wav', 'w')
  File "/usr/lib/python3.4/wave.py", line 499, in open
    return Wave_write(f)
  File "/usr/lib/python3.4/wave.py", line 293, in __init__
    f = builtins.open(f, 'wb')
PermissionError: [Errno 13] Permission denied: 'sound.wav'

EDIT: found a quick fix - use /tmp/sound.wavas filename.

In addition I have a hard time to get any of my requests recognized as speech-to-text returns lower case, e.g. "give me an a4" and the note names are currently coded in upper case "A4".

The soundfile sounds very synthetic...
