age author description
2020-04-09 Chris Cannam Unify various vectors to our base floatvec_t type; store columns in fft model cache at their desired height so we can return a reference (speeding up the peak-frequency spectrogram in particular)
2020-04-03 Chris Cannam Rewrite all the DelimitedDataString stuff so as to return vectors of individual cell strings rather than having the classes add the delimiters themselves. Rename accordingly to names based on StringExport. Take advantage of this in the CSV writer code so as to properly quote cells that contain delimiter characters. sensible-delimited-data-strings
2020-01-10 Chris Cannam Add optional ability to write a header on delimited data output, & to write times in frames
2019-09-25 Chris Cannam Some tidying time-frequency-boxes
2019-09-17 Chris Cannam More graceful handling of failure to construct FFT models in the case where the source model has already been deleted before this occurs
2019-09-12 Chris Cannam Support optional max frequency setting, useful when we want to store caches of very constrained frequency ranges (as in melodic-range spectrogram, potentially)

2015-06-12 Chris Cannam Gut the old code, but don't replace it yet (so nothing will link yet) simple-fft-model
