  -b 5.5.3 -Afn Audio::FindChunks -x wavestats

0.02 The lame reader was faulty; add --silent and an extra '-'.

        Reading from a pipe would fail (such as for MP3) due to sysread vs read
        Detection of a short read was wrong too...
        Allow caseless match of file types...
        Test that output_blocks(), output_levels() do not die too...
        Add mp3 split via MP3::Splitter.

0.03 End silence was erroneously subject to min_actual_silence_sec filter.

                Introduce new entries min_start_silence_sec,
                min_end_silence_sec, min_boundary_silence_sec.
        Examples of split_file().
        In documentation: change dependencies *sec => chunks.
        (!!!) Uncompatible change to optional arguments of split_file().
        New parameter to output_blocks(); make output more machine-readable.
        Make set(), output_level(), output_blocks() return $self, thus
                making them chainable: $self->set(...)->output_()->....

0.04 Run test extraction twice (without/with tmp.rms).

        make `make clean' to clean test temporaries.
        Allow for shortsize > 2 and longsize > 4 starting with v5.6.0.
        Correct capitalization of dB in output_levels().
        Improve docs for output_levels(), output_blocks().
        Test could loop indefinitely due to while (--$c) done on an FP value.
        Set AUDIO_FH_TEST_UNLINK=0 in environment to keep the .wav file.

0.05 Use sysread() instead of <> to read RMS (gives better alignment).

1.00 Remove a spurious ";" in .xs.

        More 5.005-compatibility fixes (# in pack, => on separate line).
        More output_levels() examples.
        Protect output_levels(), output_blocks() against $\.
        New functions for sanity check of sizeof().
        Decrease the size of subchunk to 7KB.
        Add low-level debugging code.
        Correct off-by-one error in le_short_sample_stats().

1.01 Protect against broken Data::Flow v1.00. 1.02 Enable remote machine-code debugging of crashes (looks like it crashes

on big-endian 64-bit machines...). 1.03 Upgrade remote machine-code debugging to v0.01. 1.04 Upgrade remote machine-code debugging to v0.02. 2.00 For pointer-conversion, append ! on pack specifier for long if supported.

Should fix the crash on 64-bit machines.
