0. I need to convert from .WAV to ASCII text file for utilizing in my script. FFMpeg can translate from .wav to .raw: ffmpeg -i input.wav -f s16le -acodec pcm_s16le output.raw. but I can't translate from .raw to .txt or .dat. I know of hexdump but I need something that works in windows. After hearing about (and seeing first hand) the annoyance of getting ready to upload a new version of a song, I figured it would probably be worth it to allow users to upload larger wav files, but then convert them to mp3. On average an mp3 converted track takes up about one tenth of the space of a wav. This essentially means that wav files up I am working on a php function to upload a .wav and also create an .mp3 version of it in the same folder. So far everything is working how it should except for when I try using: shell_exec('ffmpe Had a similar problem with ffmpeg.exe (4.3.1), but everything works fine with ffmpeg-20200802-b48397e-win64-static, since mp3_mf is not used in the standard container there (WAV/MP3 in your problem, AVI in my problem). So if you can't switch to a different ffmpeg version, you should force it to use libmp3lame, not just mp3 Need help converting a .wav RIFF WAVEfmt to MP3. I have a couple of .wav files from a Palm Pilot or possibly an old Windows Pocket PC that are in the format of a .wav RIFF WAVEfmt file. I can't play them, and would like to convert them to some modern, playable format. Raw Header: 52 49 46 46 AC 86 00 00 57 41 56 45 66 6D 74 20 28 00 00 00 19 00 You wanna demux the video.. This seperates the audio, subtitles and video from eachtoher.. With ffmpeg the command would be : ffmpeg -i file.avi -acodec copy -vn file.ac3-> Assuming AC3 is the audio codec ofc course!~ 6ZwDYp. I developing android application, Where I've asked to record the calls and convert them to WAVE(.wav) format and send to server. I am able to successfully record and save the audio in my mobile. The recorded file mime type is 3gpp, now I want to convert this 3gpp file to wav. I tried using FFMPEG but unable to convert it. I was wondering how can I convert multiple audio formats, i.e. wav, aac, m4a to mp3 at once with ffmpeg and php (not ffmpeg-php)? So if this: ffmpeg -i son_origine.avi -vn -ar 44100 -ac 2 -ab 192 -f mp3 son_final.mp3. Converts wav to mp3, how can I add multiple extensions in there? This command also works perfect. I cropped my music from 0 seconds to 30 seconds. Here test.mp3 is input file and temp.mp3 is output file.-ss: Indicates the starting point.-to: Indicates where to stop.-y : force output file to overwrite. ffmpeg -i test.mp3 -ss 00:00:00 -to 00:00:30 -c copy -y temp.mp3 WAV to MP3 With FFmpeg. Similar to videos, you can do the same conversions for audio files. For example, you can convert a WAV audio file to MP3 as follows: ffmpeg-i example-wav.wav-vn-ar 48000 -ac 2 -b:a 256 output.mp3. This command has more parameters than the video conversion method, but they are not difficult to understand. To explain these: I have long suspected this was the issue. For a small mp3 file that I have used as a test case, the wav file created by ffmpeg gives a numpy array of length 57339 for each channel, while the Audacity-built wav produced arrays of length 59904 in each channel - 2565 additional integers.But even if I try shifting the longer array relative to the whisper.cpp only supports wav-files. I have files in other formats I want to transcribe. It would be nice if I could make the conversion and transcription in one step/using a one-liner. I have tried these two, and some variant, but they failed:
