![]() So which one is it: 16-bit or 32-bit? Or is it 16-bit per channel?Īnd how many channels does it have? 2 as in Stereo or 5 as in DTS? The info is again conflicting. The goal of this exercise is to segregate all files> 16 bits to another directory. Some quick math yields 1411 ∕ 44.1 ≈ 31.995465, which implies a 32-bit sample size. Selected audio codec: afm: ffmpeg (FFmpeg DTS)ĪO: 44100Hz 2ch floatle (4 bytes per sample)Īnd if I play it with VLC which also outputs actual sound, it reports: Type: Audio Opening audio decoder: FFmpeg/libavcodec audio decodersĪUDIO: 44100 Hz, 2 ch, floatle, 1411.2 kbit/50.00% (ratio: 176400->352800) MediaInfo provides you with a quick access to the inner values of your audio and video files. Moreover, you can refer to the video metadata data in the file explorer and copy it to the text file. Pull down the slider, in the ' Creation Date ' position, you can view the file creation date. MPlayer 1.1-4.8 (C) 2000-2012 MPlayer Team Pull down the slider, in the audio ' bit rate ' position, you can check the bit rate in kbps. While MPlayer outputs actual sound, and seems to detect a DTS format: mplayer file.wav Selected audio codec: Uncompressed PCM ĪUDIO: 44100 Hz, 2 ch, s16le, 1411.2 kbit/100.00% (ratio: 176400->176400)ĪO: 44100Hz 2ch s16le (2 bytes per sample) geekliv-inspiron: mediainfo file.wav General Complete name : file.wav Format : Wave File size : 33. MPlayer2 2.0-701-gd4c5b7f-2ubuntu2 (C) 2000-2012 MPlayer Teamĭetected file format: WAV / WAVE (Waveform Audio) (libavformat) MediaInfo is a convenient unified display of the most relevant technical and tag data for video and audio files. MPlayer2 reports the following (but I can only hear noise): mplayer file.wav Sample Encoding: 16-bit Signed Integer PCM soxi file.wavĭuration : 00:03:19.56 = 8800596 samples = 14967 CDDA sectors MediaInfos Overall bit rate vs Maximum Overall bit rate. Also, it is possible to export the data in CVS, HTML or TXT format. This application will take care of displaying all this information in different ways, such as in a simple sheet, in plain text, tree structure, HTML format, etc. Then, deploy that file as a Lambda function. To deploy it, first create a deployable zip file containing just the app.py file, like this: zip app.zip app.py. You can find a Lambda function that prints all the information MediaInfo provides about a video file here on GitHub. how many bits are in a sample) and the number of channels. MediaInfo is a free program that allows us to access and view all the metadata that our audio and video files contain. Step 3: Deploy an AWS Lambda function that uses MediaInfo. ![]() I've got this wonderful conundrum with a WAV file, whereas I cannot detect it's actual sample size (i.e.
