Sonic-Pi: Duration with Envelopes

Which statement about amplitude is true?

• All audible sounds start and end silent and contain some non-silent part in-between

• All audible sounds end silent and contain some non-silent part in-between

True or False?

An amplitude of 0 is silence and an amplitude of 1 is normal volume.

• True

• False

The only part of the envelope that’s used by default is the ____________ _______

The ____________ _________ is the time it takes for the synth’s sound to fade out.

True or False?

All synths have a release time of 1 which means that by default they have a duration of 1 beat

• True

• False

The duration of 1 beat has a default BPM of _____ and lasts 1 second)

You can change the _______________ of your sound by changing the release time.

By default, the attack phase is _____ for all synths

True or False?

Sonic Pi’s ADSR envelopes have the following phases:

1. attack - time from 0 amplitude to the attack_level,

2. decay - time to move amplitude from attack_level to decay_level,

3. sustain - time to move the amplitude from decay_level to sustain_level,

4. release - time to move amplitude from sustain_level to 0

• True

• False

The attack phase is the time from __ __________to the attack_level
