  • Converting From 4-bit RAW Audio to WAV (or another output format)

    10 février 2017, par Haravikk

    Okay, so I’ve got some .raw files from an old game (Zork Nemesis) and determined that they’re audio files, however I’m having trouble converting them into something meaningful.

    With a bit of trial and error in Audacity I’ve found that I can listen to a still noisy version of the audio using raw file input settings of 8-bit signed PCM in stereo with a sample rate of 22050hz. However, my suspicion is that the files may in fact be encoded in 4-bits with a sample rate of 44100hz, but I’m having trouble finding a tool that can handle this.

    What I’m looking for is either a tool that can handle 4-bit raw formats, or even a tool that can determine (or guess at) the format of a given .raw file, so I know for sure what I’m dealing with (as I’m just going by trial and error so far).

    I’ve tried sox, but I’m most likely doing something wrong as it complains of an unsupported size :

    sox -r 44100 -e signed -b 4 -c 2 in.raw out.wav

    I was also going to try ffmpeg, but I can’t find the appropriate format/codec to set.

    In case it gives any further clues ; I’ve tried various combinations of settings, increasing sample size while decreasing sample rate increases the (white-)noise, and even 8-bit is still noisy, which is why I’m thinking 4-bit. I’ve tried signed and unsigned, which strangely doesn’t seem to make much of a difference

  • android - ffmpeg output audio contains garbled sound at the end

    31 mai 2017, par Sha

    I’m converting an audio (recorded via android phone with output type MPEG_4 and encoder DEFAULT) to mp3 using ffmpeg like this :

    -y -i /data/user/0/com.whispero.mithoo/files/input.mp3 -codec:a libmp3lame -qscale:a 2 /data/user/0/com.whispero.mithoo/files/output.mp3

    if the input audio is >20 seconds, there’s garbled audio at the end in the converted output file, otherwise if it’s <20 seconds, the output is fine.

    My MediaRecorder settings are :

    mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
    
mRecorder.setAudioSamplingRate(24000);
    
mRecorder.setAudioEncodingBitRate(32000);
    
Log.e("Path","Createdfilepath:"+mFile.getPath());
    
mRecorder.setOutputFile(mFile.getPath());
    
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);

  • FFMPEG Concat protocol does not combine video files

    16 septembre 2015, par Michael Erwin

    So I’ve tried using the following command to combine 2 video files with the same codec :

    ffmpeg -i "concat:/home/mike/downloads/a1.mp4|/home/mike/downloads/a2.mp4" -c copy "/home/mike/downloads/output.mp4"

    The the result : output.mp4 only contains video from a1.mp4. I also tried 2 or more file but the result is the same. What could be the possible cause for this ? Please help

    Mike
