1. A media file marking system, the media file marking system for custom marking media files, said media file marking system comprising: data processing means; data extraction means, the data extraction means being associated with the data processing means for enabling waveform data extraction from media file data, the waveform data comprising length segment values, the waveform data extraction being relative to a data extraction baseline for extracting trough-to-baseline and peak-to-baseline length segment values; summary statistic derivation means, the summary statistic derivation means being associated with the data processing means for deriving calculated statistical values for the length segment values, the calculated statistical values being for the trough-to-baseline and peak-to-baseline length segment values; custom marker generation means, the custom marker generation means being associated with the data processing means for generating a custom marker based on derived summary statistics; and marker association means, the marker association means being associated with the data processing means for respectively associating generated custom markers with the media file data for forming marked media file data.
