What needs to be clarified
The task is to assess how clipping affects the disputed remark’s intelligibility, distinguishing observed features from their interpretation. The assessment must consider the suitability of each item and whether the grounds for the proposed conclusion can be checked.
Materials to prepare
- Original audio in the device’s recording format
- Amplified and noise-reduced copy
- Disputed intervals and microphone information
What to compare
Examine flat waveform peaks, recurring maximum levels and spectral distortion; compare original and processed versions, marking audible words separately from unresolved passages. Every significant feature is linked to a specific part of the material. Similarities and differences are assessed together, considering alternative explanations and the limitations of the examination method.
Possible outcome of the analysis
A possible deliverable is a technical assessment and intelligibility annotation, with verifiable examples and reasons for the assessment. Unresolved questions and additional examinations needed are stated separately, without promising an answer in advance.
Limits of the conclusions
Reconstruction of clipped samples does not confirm the exact original speech. Conclusions are confined to the examined items and stated conditions; insufficient features require an explicit finding that the relevant question cannot be resolved.
