Examples Resample the input audio to 44100Hz: 📋 aresample= 44100 Use the aresample audio filter instead. It changes the sample rate, channel layout, or sample format of Options may be set by specifying - optionvalue in the FFmpeg tools, option = value for the aresample filter, by setting the value explicitly in the SwrContext options or using the libavutil/opt. In particular it allows one to perform audio resampling, audio channel layout rematrixing, and To invoke ffmpeg with the SoX Resampler, the option -af aresample=resampler=soxr should be given; e. dev, Windows) along these lines: . h API for The filter accepts the syntax [sample_rate:]resampler_options, where sample_rate expresses a sample rate and resampler_options is a list of key=value pairs, separated by ":". In libavfilter, a filter can have multiple inputs and multiple outputs. To illustrate the sorts of things that are possible, we consider the following Resample the input audio to the specified parameters, using the libswresample library. What the aresample filter does is quite different from that of the asetrate filter, but in any case you will Filtering in FFmpeg is enabled through the libavfilter library.

The FFmpeg resampler provides a high-level interface to the libswresample library audio resampling utilities. See the "Resampler The filter accepts the syntax [sample_rate:]resampler_options, where sample_rate expresses a sample rate and resampler_options is a list of key=value pairs, separated by ":". See the ffmpeg-resampler The ffmpeg-resampler is a lightweight command-line tool from the FFmpeg project designed specifically for high-quality audio resampling. 5 fork: hardware video transcode (NVENC/NVDEC/QSV/AMF + AV1), NPU/DirectML AI filters, CCD-aware threading, vendor-neutral GPU compute - ikeno-web/ffmpeg-gpu-npu-av1 Basic example ffmpeg -i input. Initially I used the following which did not work, the audio was playing too late towards Sometimes the audio has gaps in the live stream and the audio goes out of sync from that point on, I have managed to fix this using aresample=async=1.

See the ffmpeg-resampler I have an audio filter_complex in ffmpeg (4. Using ffmpeg to do this works fine, but you will probably end up with the audio being out of sync like I did. The idea is to have a high enough sampling rate using aresample, then divide the audio into equal chunks, each equaling 1/20th of a second, using asetnsamples.
