Abstract

Audio capture based on logarithmic conversion. At least some of the illustrative embodiments are methods including capturing audio represented by an electrical signal, the electrical signal having both positive voltage portions and negative voltage portions. In some cases, the capture is by: performing logarithmic analog-to-digital conversion on the positive voltage portions to create a first plurality of digital values; and performing logarithmic analog-to-digital conversion on the negative voltage portions to create a second plurality of digital values; and storing representations of the first and second plurality of digital values to a storage medium.
