Reducing/removing clipping in SoX when converting the sample rate
As suggested by the tool, try reducing the volume slightly, e.g. by preceding with -v 0.99 (or 0.98 etc.). Such small changes in volume are imperceptible. Example: sox -v 0.99 <source_wav> -b 16 <dest_wav> channels 1 rate 16000 trim <startTime> =<endTime> If you still get clipping then the audio is likely severely clipped (i.e. disorted) … Read more
Detecting audio silence in WAV files using C#
Audio analysis is a difficult thing requiring a lot of complex math (think Fourier Transforms). The question you have to ask is “what is silence”. If the audio that you are trying to edit is captured from an analog source, the chances are that there isn’t any silence… they will only be areas of soft … Read more
Smallest audio file: MP3, Ogg, or Wav?
Of those three, Ogg would usually be smaller than MP3. Both would be much smaller than the uncompressed WAV. Of course, there may be other factors that come into play for your site such as quality (not too much of a noticeable difference for most purposes) and browser support for each type. The file size … Read more
How to generate the audio spectrum using fft in C++? [closed]
There are quite a few similar/related questions on SO already which are well worth reading as the answers contain a lot of useful information and advice, but in essence you need to do this: Convert the audio data to the format required by FFT (e.g. int -> float, with separate L/R channels); Apply suitable window … Read more
Note onset detection
Here is a graphic that illustrates the threshold approach to note onset detection: This image shows a typical WAV file with three discrete notes played in succession. The red line represents a chosen signal threshold, and the blue lines represent note start positions returned by a simple algorithm that marks a start when the signal … Read more
Could not find tag for codec pcm_alaw in stream #1, codec not currently supported in container when concatenating 2 files using ffmpeg [closed]
codec not currently supported in container ffmpeg does not support PCM (pcm_alaw, pcm_s16le, etc) in the MP4 container. Encode the audio as AAC, or use a different output container format such as MOV or MKV. Encode the audio to AAC ffmpeg -i input.mov -c:v copy -c:a aac output.mp4 Or output to MOV or MKV ffmpeg … Read more
using FFMPEG with silencedetect to remove audio silence
Use the silenceremove filter. This removes silence from the audio track only – it will leave the video unedited, i.e., things will go out of sync Its arguments are a little cryptic. An example ffmpeg -i input.mp3 -af silenceremove=1:0:-50dB output.mp3 This removes silence at the beginning (indicated by the first argument 1) with minimum length … Read more
