Parameters ---------- file : str or int or file-like object The file to write to. See `SoundFile` for details. data : array_like The data to write. Usually two-dimensional (frames x channels), but one-dimensional *data* can be used for mono files. Only the data types ``'float64'``, ``'float32'``, ``'int32'`` and ``'int16'`` are supported. .. note:: The data type of *data* does **not** select the data type of the written file. Audio data will be converted to the given *subtype*. Writing int values to a float file will *not* scale the values to [-1.0, 1.0). If you write the value ``np.array([42], dtype='int32')``, to a ``subtype='FLOAT'`` file, the file will then contain ``np.array([42.], dtype='float32')``. samplerate : int The sample rate of the audio data. subtype : str, optional See `default_subtype()` for the default value and `available_subtypes()` for all possible values. Other Parameters ---------------- format, endian, closefd, compression_level, bitrate_mode See `SoundFile`. Examples -------- Write 10 frames of random data to a new file: >>> import numpy as np >>> import soundfile as sf >>> sf.write('stereo_file.wav', np.random.randn(10, 2), 44100, 'PCM_24') rNrw)numpyasarrayndimshaperwrite) rrrrrrrrrnprrs rrrAs` ::d  D yA~~:a= 4j(FFG$l 4 478  s A00A47A4 blocksizeoverlapc #Kt|d| | | || |5}||||}|||||||| Ed{VddddS#1swxYwYdS)a8Return a generator for block-wise reading. By default, iteration starts at the beginning and stops at the end of the file. Use *start* to start at a later position and *frames* or *stop* to stop earlier. If you stop iterating over the generator before it's exhausted, the sound file is not closed. This is normally not a problem because the file is opened in read-only mode. To close the file properly, the generator's ``close()`` method can be called. Parameters ---------- file : str or int or file-like object The file to read from. See `SoundFile` for details. blocksize : int The number of frames to read per block. Either this or *out* must be given. overlap : int, optional The number of frames to rewind between each block. Yields ------ `numpy.ndarray` or type(out) Blocks of audio data. If *out* was given, and the requested frames are not an integer multiple of the length of *out*, and no *fill_value* was given, the last block will be a smaller view into *out*.

If a file is opened with `mode` ``'r'`` (the default) or ``'r+'``, no sample rate, channels or file format need to be given because the information is obtained from the file. An exception is the ``'RAW'`` data format, which always requires these data points. File formats consist of three case-insensitive strings: * a *major format* which is by default obtained from the extension of the file name (if known) and which can be forced with the format argument (e.g. ``format='WAVEX'``). * a *subtype*, e.g. ``'PCM_24'``. Most major formats have a default subtype which is used if no subtype is specified. * an *endian-ness*, which doesn't have to be specified at all in most cases. A `SoundFile` object is a *context manager*, which means if used in a "with" statement, `close()` is automatically called when reaching the end of the code block inside the "with" statement. Parameters ---------- file : str or int or file-like object The file to open. This can be a file name, a file descriptor or a Python file object (or a similar object with the methods ``read()``/``readinto()``, ``write()``, ``seek()`` and ``tell()``). mode : {'r', 'r+', 'w', 'w+', 'x', 'x+'}, optional Open mode. Has to begin with one of these three characters: ``'r'`` for reading, ``'w'`` for writing (truncates *file*) or ``'x'`` for writing (raises an error if *file* already exists). Additionally, it may contain ``'+'`` to open *file* for both reading and writing. The character ``'b'`` for *binary mode* is implied because all sound files have to be opened in this mode. If *file* is a file descriptor or a file-like object, ``'w'`` doesn't truncate and ``'x'`` doesn't raise an error. samplerate : int The sample rate of the file. If `mode` contains ``'r'``, this is obtained from the file (except for ``'RAW'`` files). channels : int The number of channels of the file. If `mode` contains ``'r'``, this is obtained from the file (except for ``'RAW'`` files). subtype : str, sometimes optional The subtype of the sound file. If `mode` contains ``'r'``, this is obtained from the file (except for ``'RAW'`` files), if not, the default value depends on the selected `format` (see `default_subtype()`). See `available_subtypes()` for all possible subtypes for a given `format`. endian : {'FILE', 'LITTLE', 'BIG', 'CPU'}, sometimes optional The endian-ness of the sound file. If `mode` contains ``'r'``, this is obtained from the file (except for ``'RAW'`` files), if not, the default value is ``'FILE'``, which is correct in most cases. format : str, sometimes optional The major format of the sound file. If `mode` contains ``'r'``, this is obtained from the file (except for ``'RAW'`` files), if not, the default value is determined from the file extension. See `available_formats()` for all possible values. closefd : bool, optional Whether to close the file descriptor on `close()`. Only applicable if the *file* argument is a file descriptor. compression_level : float, optional The compression level on 'write()'. The compression level should be between 0.0 (minimum compression level) and 1.0 (highest compression level). See `libsndfile document `__. bitrate_mode : {'CONSTANT', 'AVERAGE', 'VARIABLE'}, optional The bitrate mode on 'write()'. See `libsndfile document `__. Examples -------- >>> from soundfile import SoundFile Open an existing file for reading: >>> myfile = SoundFile('existing_file.wav') >>> # do something with myfile >>> myfile.close() Create a new sound file for reading and writing using a with statement: >>> with SoundFile('new_file.wav', 'x+', 44100, 2) as myfile: >>> # do something with myfile >>> # ... >>> assert not myfile.closed >>> # myfile.close() is called automatically at the end >>> assert myfile.closed Nr z6Can not get `mode` from file. provided `mode` is None.zr+r) isinstance_osPathLikefspath_namegetattrr _check_mode_mode_compression_level _bitrate_mode_create_info_struct_info_open_fileset issupersetseekableseekr sf_commandSFC_SET_CLIPPINGrNULLSF_TRUE_set_compression_level_set_bitrate_mode) rrr rrrrrrrrmode_ints rrzSoundFile.__init__OspP dCL ) ) $:d##D <4..D| XYYYt$$ "3)(tZ)/&BB ZZh88 t99   % % $--//  IIaLLL  D$949  & & &  " .

Reads the given number of frames in the given data format starting at the current read/write position. This advances the read/write position by the same number of frames. By default, all frames from the current read/write position to the end of the file are returned. Use `seek()` to move the current read/write position. Parameters ---------- frames : int, optional The number of frames to read. If ``frames < 0``, the whole rest of the file is read. dtype : {'float64', 'float32', 'int32', 'int16'}, optional Data type of the returned array, by default ``'float64'``. Floating point audio data is typically in the range from ``-1.0`` to ``1.0``. Integer data is in the range from ``-2**15`` to ``2**15-1`` for ``'int16'`` and from ``-2**31`` to ``2**31-1`` for ``'int32'``. .. note:: Reading int values from a float file will *not* scale the data to [-1.0, 1.0). If the file contains ``np.array([42.6], dtype='float32')``, you will read ``np.array([43], dtype='int32')`` for ``dtype='int32'``. Returns ------- audiodata : `numpy.ndarray` or type(out) A two-dimensional NumPy (frames x channels) array is returned. If the sound file has only one channel, a one-dimensional array is returned. Use ``always_2d=True`` to return a two-dimensional array anyway. If *out* was specified, it is returned. If *out* has more frames than available in the file (or if *frames* is smaller than the length of *out*) and no *fill_value* is given, then only a part of *out* is overwritten and a view containing all valid frames is returned. Other Parameters ---------------- always_2d : bool, optional By default, reading a mono sound file will return a one-dimensional array. With ``always_2d=True``, audio data is always returned as a two-dimensional array, even if the audio file has only one channel. fill_value : float, optional If more frames are requested than available in the file, the rest of the output is be filled with *fill_value*. If *fill_value* is not specified, a smaller array is returned. out : `numpy.ndarray` or subclass, optional If *out* is specified, the data is written into the given array instead of creating a new array. In this case, the arguments *dtype* and *always_2d* are silently ignored! If *frames* is not given, it is obtained from the length of *out*. Examples -------- >>> from soundfile import SoundFile >>> myfile = SoundFile('stereo_file.wav') Reading 3 frames from a stereo file: >>> myfile.read(3) array([[ 0.71329652, 0.06294799], [-0.26450912, -0.38874483], [ 0.67398441, -0.11516333]]) >>> myfile.close() See Also -------- buffer_read, .write Nrr) _check_frames_create_empty_arraylen _array_io)rrrrrrs rrzSoundFile.readksb ;'' ;;F**69eDDCCzzVc#hh..SV44 s88f  !'6'l)FGG  rc||d}||}tj|dz||jz}|d|||}||ksJtj|S)aRead from the file and return data as buffer object.
