To generate a waveform using the audiowaveform library, we need to do it in two steps.
Step 1: Create a binary format (.dat) file from the audio file
audiowaveform -i 3.mp3 -o 3.dat -z 256 -b 8
Step 2: Generate a image (.png) file using the binary data
audiowaveform -i 3.dat -o 3.png -z 256

audiowaveform is a C++ command-line application that generates waveform data from either MP3, WAV, FLAC, Ogg Vorbis, or Opus format audio files. Waveform data can be used to produce a visual rendering of the audio.
How to Install
https://github.com/bbc/audiowaveform?tab=readme-ov-file#installation
Install on Ubuntu
sudo add-apt-repository ppa:chris-needham/ppa
sudo apt-get update
sudo apt-get install audiowaveform
#Linux #Ubuntu #audiowaveform #waveform #MP3 #WAV #FLAC #Ogg #Vorbis #Opus
So... how about decoding of Ogg Vorbis streams in pure Common Lisp? As in, no C-bindings here (except libao for the final audio output, obviously). All the decoding is done natively in Lisp.
I'll integrate this into #Benben later today.
The code is part of my CL-RemiAudio library: https://chiselapp.com/user/MistressRemilia/repository/cl-remiaudio/
#CommonLisp #lisp #LinuxAudio #vorbis
and the above should've been on the #taggart thread instead of here, but we've already established that i suck at keeping all my updates to a single thread...
anyway, first issue closed! #lofty worked great, giving me uniform support for *takes a deep breath* #Aac #Aiff #Ape #Flac #Mpeg #Mp4 #Mpc #Opus #Vorbis #Speex #Wav #WavPack 💥
up next: using https://docs.rs/unicode-width/latest/unicode_width/ to get me some tidy columns - length of some release titles is just delightfully absurd!
@jbz to some extent it is good because it #divest|s and #defund|s #PatentTrolls like #Sisvel who harrassed busonesses all the time.

Хм... Судя по тестам — #Opus действительно лидер. А я, блин, по старинке в #Vorbis кодирую... И это на 192 килобитах, при том, что ему можно и > 320 выставить.

El álbum "Pequeño" de #Bunbury me sigue pareciendo bueno. Me gusta la letra de la canción "De mayor": De pequeño me enseñaron a querer ser mayor / De mayor voy aprender a ser pequeño / Y asi cuando cometa otravez el mismo error /Quizas no me lo tengas tan encuenta.
Además lo tengo asociado a una época feliz donde estaba descubriendo el software libre. Creo que estaba con mi @kde_espana tres con mi CD convertido a #OGG #Vorbis, je je.
@getimiskon That being said there's nothing wrong using #GIMP and I'd rather use that than to ever give #Adobe or #AVID money.
So yeah, I do want to see #Linux ports of #Affinity's Suite and #Blackmagicdesign to step up their Support of #DavinchiResolve for Linux outside of #CentOS & #RHEL Workstation and at least on the #paid version get #FeatureParity to the #macOS & #Windows version in terms of #Codecs (or at least implement support for those not subject to #licensing like #AV1, #VP9 / #WebM & #Opus, #Vorbis & #Speex.
FFmpeg, Ogg Vorbis, and FLAC are key technologies in the world of multimedia processing, each serving a unique purpose. FFmpeg is a powerful, open-source suite for converting, streaming, and manipulating audio and video files across various formats. Ogg Vorbis is a free, open-source lossy codec known for its efficient compression and high-quality audio, ideal for streaming.

@nixCraft No just no. I have a Samsung phone over here which Samsung has deliberately slowed down after three and a half years of work
A perfectly fine phone
I have to root it and put Linux on it in order to use the thing
Right now that Android is just a glorified #Ogg #Vorbis player

did you know that there is an extended #tracker modules (XM) extension where samples are #vorbis encoded?
i did, and i spent the last 2-3 days working on a commandline converter since the 'official' one seems to be abandonware
Mp3Splt-project is a utility to split mp3, ogg vorbis and native FLAC files selecting a begin and an end time position, without decoding.
Unfortunately, the last released was back in 2014.
New wiki note:
💬 Effective speech #compression with #Vorbis audio format. #oggvorbis

No I did not just release some swift bindings for libogg, libvorbis and libopus on my github because the only existing versions I could find were unmaintained and written in a weird way.
I'd never ever do such a thing.
Really.
