Will (when used with mp3_split_read() and default options) keep all MP3 frames (the current implementation removes all the non-frame information from the file this may/should change in the future). The file with piece description 0 # Copy whole file (0.INF), and update Xing header If overwrite is false (default), it is a fatal error if a file with the target name exists. Other recognized options: verbose, overwrite and lax the last one means the how early the mp3 file can end before the end of the last chunk so that an error condition is not rised the default is 0.02 (in sec), use some ridiculously large value (such as 1e100 if EOF is never an error). If keep_Xing option is true, and the initial file contained an Xing frame, an Xing frame with estimated values for the number of frames and the length of the output file is emited if update_Xing option is true, this frame is updated to reflect actual size of the piece (and positions of 99 intermediate moments) when the piece is finished. The prepend and append callback can actually write data (with a buffered write) to filehandle, or return the string to write. The default value of piece_name callback uses the piece names of the form "03_initial_name.mp3", by default the other callbacks are NO-OPs. $pieceNum is 1 for the first piece to write. $piece_name, $cur_total_frames, $piece_frames, $xing_written, $Xing, $opts, $pieceFileHandle) Īfter_write($mp3name, $piece, $pieceNum, $cur_total_time, $piece_time, $pieceFileName, $cur_total_frames, $piece_frames, Prepend($pieceNum, $mp3name, $piece, $Xing, $opts,Īppend( $mp3name, $piece, $pieceNum, $cur_total_time, $piece_time, The following callback options should be function references with signatures name_callback($pieceNum, $mp3name, $piece, $Xing, $opts) # returns file name Note that this is a format of method output_blocks() of Audio::FindChunks. START and END are exactly the same as in the description of pieces for mp3split() however, END may be omited (with the same meaning as 'INF'). Each line of the description file should be either empty (except comments), or have the form START END # OPTIONAL_COMMENT Similarly, mp3split_read() takes names of an MP3 file and of a file with the description of pieces, followed by optional reference to a hash of options. The remaining elements of a piece description should form a hash of piece-specific options (arbitrary user data can be stored with the key user). Similarly, one can put the absolute position of the end-of-the-piece in the duration field by prepending the time by = if this field has a special value 'INF', it is assumed to go until the start of the next piece, or until the audio ends. the end of previous piece (or start of file) to do this, prepend > to the field. Alternatively, one can specify the start field as a relative position w.r.t. Such a description is an array reference with the start and duration of the piece (in seconds or of the forms 03h05m56.45, 03h05m56.45s, or 03:05:56.45 any of the hours/minutes/seconds fields can be omited if the result is not ambiguous. The first two arguments of mp3split() is a name of an MP3 file and a reference to a hash of options, the remaining are descriptions of pieces. ![]() # up to 10sec before expected end of chunk, this is not considered a failure. # the second starts at 389sec, preferable length 615sec, but if EOF is met # Split 2 chunks from a file: the first starts at 3sec, length 356.25sec RecorderRecord computer sounds from streaming media and microphone at the same time and output into multiple audio formats.MP3::Splitter - Perl extension for splitting MP3 files SYNOPSIS use MP3::Splitter Many effects, such as fade in/out, speed adjustment, music mixing, are available.
