Abstract:
1. A method comprising: reading at least a subset of audio content comprising an audio file from optical media removably integrated with an optical drive, wherein the reading comprises: reading a sector of audio content, wherein the reading of the sector is based on amplitude information of the sector; determining whether additional sector reads of the audio content are necessary, based on a particular read size of the optical drive; and iteratively repeating the reading step using different sizes, if it is determined if the additional sector reads are necessary; analyzing at least the read subset of audio content to quantify optical drive read accuracy of the audio content, comprising comparing a first bundle of audio content from one sector of audio content to a second bundle of audio content from the one sector; and measuring a difference in amplitude between the first bundle and the second bundle to quantify intra-sector misalignment; and generating one or more metrics of optical drive read accuracy based, at least in part, on the analysis of the read subset of audio content.
