Summary
Returns generated mono audio as a flat samples array instead of preserving a singleton channel dimension from the ONNX output.
Why
Direct audio pipelines commonly expect mono audio as
(samples,). With the previous(1, samples)shape, user code such asnp.stack([audio, audio], axis=1)produces an unexpected 3D array rather than(samples, channels), which can lead to incorrect playback behavior in downstream audio tools.Addresses #112.
Validation
python3 -m unittest -qkittentts,normalize_text, andmono_audio_array.KittenML/kitten-tts-nano-0.8-int8, asserting the returned audio is one-dimensional float32 audio.
