Can you post the headers sent by the server both with and without the PHP script? I’m wondering if the PHP script is sending a different Content-Type than serving the files normally. It would also be a good idea to specify the type attribute on the source elements, so the browser does not have to … Read more
This two step process should work Step 1 Pad out the audio in each segment ffmpeg -i segment1.mov -af apad -c:v copy <audio encoding params> -shortest -avoid_negative_ts make_zero -fflags +genpts padded1.mov Or Generate segments with synced streams ffmpeg -y -ss 00:00:02.750 -i input.MOV -c copy -t 00:00:05.880 -avoid_negative_ts make_zero -fflags +genpts segment.MOV Step 2 Concat … Read more
The short answer is that you need much more than one algorithm. Good chord recognition methods could more aptly be described as “systems”, but usually they are indeed based on an initial transform to the frequency domain (most often DFT). If you want a chord representaton of the song similar to this C G Am … Read more

just use: soxi <filename> or sox –i <filename> to produce output such as: Input File : ‘final.flac’ Channels : 4 Sample Rate : 44100 Precision : 16-bit Duration : 00:00:11.48 = 506179 samples = 860.849 CDDA sectors File Size : 2.44M Bit Rate : 1.70M Sample Encoding: 16-bit FLAC Comment : ‘Comment=Processed by SoX’ The … Read more
.M4A files typically contain audio only and are formatted as MPEG-4 Part 14 files (.MP4 container). .AAC is not a container format and instead it is a raw MPEG-4 Part 3 bitstream with audio stream encoded. Note that M4A does not have to contain exactly AAC audio, there are other valid options as well.
The syntax is sox input output trim <start> <duration> e.g. sox input.wav output.wav trim 0 00:35 will output the first 35 seconds into output.wav. (you can know what the length is using sox input -n stat) From the SoX documentation on the trim command: Cuts portions out of the audio. Any number of positions may … Read more
The previous answer is pretty old. You can use IPython.display.Audio now. Like this: import IPython IPython.display.Audio(“my_audio_file.mp3”) Note that you can also process any type of audio content, and pass it to this function as a numpy array. If you want to display multiple audio files, use the following: IPython.display.display(IPython.display.Audio(“my_audio_file.mp3”)) IPython.display.display(IPython.display.Audio(“my_audio_file.mp3”))
There is a better way: soxi -D out.wav
The wav container just adds a simple header to the raw PCM data. The header includes the format, sample rate, and number of channels. Since the raw PCM data does not include this information, you will need to specify it on the command line. Options are specified before the file they apply to, so options … Read more
