@end table
@section atrim
Trim the input so that the output contains one continuous subpart of the input.
This filter accepts the following options:
@table @option
@item start
Timestamp (in seconds) of the start of the kept section. I.e. the audio sample
with the timestamp @var{start} will be the first sample in the output.
@item end
Timestamp (in seconds) of the first audio sample that will be dropped. I.e. the
audio sample immediately preceding the one with the timestamp @var{end} will be
the last sample in the output.
@item start_pts
Same as @var{start}, except this option sets the start timestamp in samples
instead of seconds.
@item end_pts
Same as @var{end}, except this option sets the end timestamp in samples instead
of seconds.
@item duration
Maximum duration of the output in seconds.
@item start_sample
Number of the first sample that should be passed to output.
@item end_sample
Number of the first sample that should be dropped.
@end table
Note that the first two sets of the start/end options and the @option{duration}
option look at the frame timestamp, while the _sample options simply count the
samples that pass through the filter. So start/end_pts and start/end_sample will
give different results when the timestamps are wrong, inexact or do not start at
zero. Also note that this filter does not modify the timestamps. If you wish
that the output timestamps start at zero, insert the asetpts filter after the
atrim filter.
If multiple start or end options are set, this filter tries to be greedy and
keep all samples that match at least one of the specified constraints. To keep
only the part that matches all the constraints at once, chain multiple atrim
filters.
The defaults are such that all the input is kept. So it is possible to set e.g.
just the end values to keep everything before the specified time.
Examples:
@itemize
@item
drop everything except the second minute of input
@example
avconv -i INPUT -af atrim=60:120
@end example
@item
keep only the first 1000 samples
@example
avconv -i INPUT -af atrim=end_sample=1000
@end example
@end itemize
@section channelsplit
Split each channel in input audio stream into a separate output stream.

@section trim
Trim the input so that the output contains one continuous subpart of the input.
This filter accepts the following options:
@table @option
@item start
Timestamp (in seconds) of the start of the kept section. I.e. the frame with the
timestamp @var{start} will be the first frame in the output.
@item end
Timestamp (in seconds) of the first frame that will be dropped. I.e. the frame
immediately preceding the one with the timestamp @var{end} will be the last
frame in the output.
@item start_pts
Same as @var{start}, except this option sets the start timestamp in timebase
units instead of seconds.
@item end_pts
Same as @var{end}, except this option sets the end timestamp in timebase units
instead of seconds.
@item duration
Maximum duration of the output in seconds.
@item start_frame
Number of the first frame that should be passed to output.
@item end_frame
Number of the first frame that should be dropped.
@end table
Note that the first two sets of the start/end options and the @option{duration}
option look at the frame timestamp, while the _frame variants simply count the
frames that pass through the filter. Also note that this filter does not modify
the timestamps. If you wish that the output timestamps start at zero, insert a
setpts filter after the trim filter.
