The raw audio data is specified by ``frame_data``, which is a sequence of bytes representing audio samples. This is the frame data structure used by the PCM WAV format. The width of each sample, in bytes, is specified by ``sample_width``. Each group of ``sample_width`` bytes represents a single audio sample. The audio data is assumed to have a sample rate of ``sample_rate`` samples per second (Hertz). Usually, instances of this class are obtained from ``recognizer_instance.record`` or ``recognizer_instance.listen``, or in the callback for ``recognizer_instance.listen_in_background``, rather than instantiating them directly. c|dkDsJd|dzdk(rd|cxkr dksJdJd||_||_t||_y)Nrz&Sample rate must be a positive integerz.Sample width must be between 1 and 4 inclusive) frame_data sample_rateint sample_width)selfr r r s V/var/www/auto_recruiter/arenv/lib/python3.12/site-packages/speech_recognition/audio.py__init__zAudioData.__init__slQH HH 1  !a<&<1&< < ; < <&< < ; < <$& -cddl}|j}|j|5}|j|cdddS#1swYyxYw)z8Creates a new ``AudioData`` instance from an audio file.rN)speech_recognition Recognizer AudioFilerecord)cls file_pathsrrsources r from_filezAudioData.from_file$sA ( MMO \\) $ $88F# $ $ $s AA Ncx| |dk\sJd|||dn|k\sJd|d}n(t||jz|jzdz}|t|j}n(t||jz|jzdz}t |j|||j|jS)ag Returns a new ``AudioData`` instance, trimmed to a given time interval.
