javax.sound.sampled.UnsupportedAudioFileException: no se pudo obtener la secuencia de entrada de audio desde el archivo de entrada al cargar el archivo wav

Question

Estoy usando java 6 , y estoy tratando de cargar el archivo wav , para obtener su duración de la siguiente manera:

public static double getAudioFileDuration(File file) {
        try {
            AudioInputStream stream = AudioSystem.getAudioInputStream(file);

            // At present, ALAW and ULAW encodings must be converted
            // to PCM_SIGNED before it can be played
            AudioFormat format = stream.getFormat();
            if (format.getEncoding() != AudioFormat.Encoding.PCM_SIGNED) {
                format = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED,
                        format.getSampleRate(), format.getSampleSizeInBits(),
                        format.getChannels(), format.getFrameSize(),
                        format.getFrameRate(), true); // big endian
                stream = AudioSystem.getAudioInputStream(format, stream);
            }
            DataLine.Info info = new DataLine.Info(Clip.class,
                    stream.getFormat(),
                    ((int) stream.getFrameLength() * format.getFrameSize()));
            Clip clip = (Clip) AudioSystem.getLine(info);
            // clip.open(stream);
            double durationInSecs = clip.getBufferSize()
                    / (clip.getFormat().getFrameSize() * clip.getFormat()
                            .getFrameRate());
            double minTemp = Math.round(Math.round(durationInSecs) / 60.0);
            double durationInMin = minTemp
                    + (((Math.round(durationInSecs) / 60.0) - minTemp) * 60)
                    / 100;
            return durationInMin;

        } catch (Exception e) {
            e.printStackTrace();
            return 0;
        }

    }

pero para algunos archivos WAV no puedo obtener la duración, y recibo la siguiente excepción:

¿Alguna idea de cómo solucionar esta excepción o si hay otra forma de obtener la duración del archivo?

Answer 1

... algunas ideas de cómo solucionar esta excepción, ..

Como WAV es un formato de contenedor , puede incluir cualquier cantidad de codificación internamente.

.. los archivos wav se pueden codificar con una variedad de códecs para reducir el tamaño del archivo (por ejemplo, los códecs GSM o MP3).

Ver la información de Java Sound. página para más detalles sobre cómo agregar soporte para una codificación adicional (usando el SPI), y una ventaja sobre un MP3 SPI.

¿o si hay otra forma de obtener la duración del archivo?

Realmente no. Con formatos comprimidos, la tasa de bits es variable y no hay manera de saber con certeza cuánto tiempo tarda una pista en convertirla a PCM o formatos similares, en los que la velocidad de bits es constante y el tiempo de la pista se resuelve por completo.
