For this stretch factor, the stretch effect has better performance.

Nobody has claimed this yet.

When running the below code,
```
from scipy.io.wavfile import read
import sox
import numpy as np

path = 'input.wav'
sr, wav = read(path)
tfm = sox.Transformer()
tfm.set_globals(verbosity=0)
stretch_ratio = np.random.normal(1.05,0.125)
tfm.tempo(stretch_ratio, audio_type='s')
wav = tfm.build_array(input_array=wav, sample_rate_in=sr)
```
I get a warning that says
'For this stretch factor, the stretch effect has better performance.'.

I want to turn this off, but it seems that
`
tfm.set_globals(verbosity=0)
`
does nothing.

What can I do to turn that warning off?

Start with the Transformer.set_globals(verbosity=0) and build_array(input_array=..., sample_rate_in=...) entry points shown in the report, then trace how the SoX warning reaches Python. Reproduce the warning with the provided snippet and verify that the intended verbosity setting suppresses it without preventing the tempo transformation.
