Disclosed are exemplary apparatus, techniques, algorithms and methods for reducing the size of time domain data with minimal distortion. In general, the exemplary techniques use a digital channelizer to convert a time series in to a set of frequency bins. Frequency bins that have a power less than a predefined threshold are converted to zero. The frequency domain data is then compressed using a compression routine. The compressed frequency domain data may be stored or transmitted. Recovery of the time domain data involves reversing the compaction process. Since the digital channelizer produces perfect reconstruction of the time signals, little distortion of the time domain signals occurs.
