- avoid the case len(sil_tags) == 1 that it will return empty output

If len(sil_tags) == 1, the audio should be sliced. In which case do you think the slicer does not work properly?

[nguyenlamvu123]

audio-slicer/slicer2.py:

        if silence_start is not None and total_frames - silence_start >= self.min_interval:
            silence_end = min(total_frames, silence_start + self.max_sil_kept)
            pos = rms_list[silence_start: silence_end + 1].argmin() + silence_start
            sil_tags.append((pos, total_frames + 1))
        # Apply and return slices.
        if len(sil_tags) == 0:
            return [waveform]
        else:  -------------------------------> if len(sil_tags) == 1, it will run into this
            chunks = []
            if sil_tags[0][0] > 0:
                chunks.append(self._apply_slice(waveform, 0, sil_tags[0][0]))  -------------------------------> sil_tags[0][0] < 0 and chunks is still an empty list
            for i in range(len(sil_tags) - 1):  -------------------------------> if len(sil_tags) == 1, it will be `for i in range(0):` and chunks is still an empty list
                chunks.append(self._apply_slice(waveform, sil_tags[i][1], sil_tags[i + 1][0]))
            if sil_tags[-1][1] < total_frames:
                chunks.append(self._apply_slice(waveform, sil_tags[-1][1], total_frames))  -------------------------------> if sil_tags[-1][1] >= total_frames, chunks is still an empty list
            return chunks

it is a strange story, with the same input and with if len(sil_tags) == 0:, it well runs in local (with pycharm) but is bad in remote server; well runs in remote server with if len(sil_tags) <= 1:
so I can`t take a screenshoot of debug of pycharm
