See ``AudioFileClip`` and ``CompositeAudioClip`` for usable classes. An AudioClip is a Clip with a ``frame_function`` attribute of the form `` t -> [ f_t ]`` for mono sound and ``t-> [ f1_t, f2_t ]`` for stereo sound (the arrays are Numpy arrays). The `f_t` are floats between -1 and 1. These bounds can be trespassed without problems (the program will put the sound back into the bounds at conversion time, without much impact). Parameters ---------- frame_function A function `t-> frame at time t`. The frame does not mean much for a sound, it is just a float. What 'makes' the sound are the variations of that float in the time. duration Duration of the clip (in seconds). Some clips are infinite, in this case their duration will be ``None``. nchannels Number of channels (one or two for mono or stereo). Examples -------- .. code:: python # Plays the note A in mono (a sine wave of frequency 440 Hz) import numpy as np frame_function = lambda t: np.sin(440 * 2 * np.pi * t) clip = AudioClip(frame_function, duration=5, fps=44100) clip.preview() # Plays the note A in stereo (two sine waves of frequencies 440 and 880 Hz) frame_function = lambda t: np.array([ np.sin(440 * 2 * np.pi * t), np.sin(880 * 2 * np.pi * t) ]).T.copy(order="C") clip = AudioClip(frame_function, duration=3, fps=44100) clip.preview() ct||||_|E||_|j d}t |drt t||_nd|_|||_ ||_ yy)Nr__iter__) super__init__fpsframe_function get_framehasattrlenlist nchannelsdurationend)selfrrrframe0 __class__s `/var/www/it7/html/youtubeDownloader/venv/lib/python3.12/site-packages/moviepy/audio/AudioClip.pyrzAudioClip.__init__Dsp  ?DH  %"0D ^^A&Fvz*!$T&\!2!"  $DMDH c#K| |j}tj|}|t||z}t||jz}||zdz}t j d||dzdt} |jtt|D]T} | | dz| | z } | |ksJd|z t j| | | | dzz} |j| ||||Vyw) zAIterator that returns the whole sound array of the clip by chunksNrrT)endpointdtype)chunk?)nbytesquantizer buffersize) rproglogdefault_bar_loggerintrnplinspaceiter_barrrangearange to_soundarray) r chunksizechunk_durationrr%r$logger total_sizenchunks positionsisizetimingss r iter_chunkszAudioClip.iter_chunksUs  ;((C++F3  %NS01It}},-  )A-KK:w{TQTU tE'N';< AQU#il2D9$ $$SyBIIilIa!eC/L}}|+'+~~':")) (( #hqJ)YYq$--s; NN2&  5"**T9*EFI W9&AGq6zA~.:BB7KIrc|xr|jdkD}tj|j}|j||D]1}tj|t |j d}3|r|S|dS)z-Returns the maximum volume level of the clip.r)r0r2r)axis)rr*zerosr9rDabsmax)rstereor0r2maxir"s r max_volumezAudioClip.max_volumes|.DNNQ.xx'%% &%I |s|jsd}n |j}|Rtjjtjj |\} } t | dddd}t||||||||||  S#t $r tdwxYw)a+Writes an audio file from the AudioClip. Parameters ---------- filename Name of the output file, as a string or a path-like object. fps Frames per second. If not set, it will try default to self.fps if already set, otherwise it will default to 44100. nbytes Sample width (set to 2 for 16-bit sound, 4 for 32-bit sound) buffersize The sound is not generated all at once, but rather made by bunches of frames (chunks). ``buffersize`` is the size of such a chunk. Try varying it if you meet audio problems (but you shouldn't have to). Default to 2000 codec Which audio codec should be used. If None provided, the codec is determined based on the extension of the filename. Choose 'pcm_s16le' for 16-bit wav and 'pcm_s32le' for 32-bit wav. bitrate Audio bitrate, given as a string like '50k', '500k', '3000k'. Will determine the size and quality of the output file. Note that it mainly an indicative goal, the bitrate won't necessarily be the this in the output file. ffmpeg_params Any additional parameters you would like to pass, as a list of terms, like ['-option1', 'value1', '-option2', 'value2'] write_logfile If true, produces a detailed logfile named filename + '.log' when writing the file logger Either ``"bar"`` for progress bar or ``None`` or any Proglog logger. iDNrcodecrzoMoviePy couldn't find the codec associated with the filename.

If the sound jumps during the preview, lower it (11025 is still fine, 5000 is tolerable). buffersize The sound is not generated all at once, but rather made by bunches of frames (chunks). ``buffersize`` is the size of such a chunk. Try varying it if you meet audio problems (but you shouldn't have to). nbytes: Number of bytes to encode the sound: 1 for 8bit sound, 2 for 16bit, 4 for 32bit sound. 2 bytes is fine. audio_flag, video_flag: Instances of class threading events that are used to synchronize video and audio during ``VideoClip.preview()``. )cliprr&r$ audio_flag video_flagNr)rrr&r$rerfs r audiopreviewzAudioClip.audiopreviews< !!!  rcdt|tr t||gStt||SN) isinstancer concatenate_audioclipsr__add__)rotherrs rrlzAudioClip.__add__6s. eY ')4-8 8Y-e44r)NNN)NNNFr;N)NNFr;P)FrnN)Nr;NNNFbar)Nror;NN)__name__ __module__ __qualname____doc__rrr9r/rSrrbrgrl __classcell__rs@rr r s-^ " <FK22h +J' U (U nOS$ $ L55rr ceZdZdZdZy)AudioArrayClipa An audio clip made from a sound array.
