Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

not able to convert a specific .wav file to mp3 or m4a with sox, avconv
25 juillet 2017, par astrographAt the office we have a project where we apply IoT technologies to a real bee hive.
One of the features is to detect specific sounds the bees make when a new queen hatches. We have a special microphone in place, the algorithm is also implemented. For now we get a lot of false positives, and want to quickly be able to identify them, by listening to the audio files in the browser. Therefore I want to convert the .wav files to either .mp3 or .m4a
The .wav file format seems to be quite strange, as I was not able to convert it to mp3 using avconv, sox or even audacity. The funny thing is, the Microsoft media player can play the .wav file fine.
Here is the information soxi gives about the wav file :
pi@raspberrypi:~ $ soxi Channel1.wav
soxi WARN wav: wave header missing extended part of fmt chunk
Input File : 'Channel1.wav'
Channels : 1
Sample Rate : 6250
Precision : 24-bit
Duration : 00:01:21.00 = 506250 samples ~ 6075 CDDA sectors
File Size : 2.03M
Bit Rate : 200k
Sample Encoding: 32-bit Floating Point PCMThis is the avconv command I am trying to use :
avconv -y -v quiet -i Channel1.wav -strict experimental -ar 44100 -ab 160k Channel1.m4a
I also tried with sox :
sox -v 0.60 Channel1.wav -r 22050 Channel1.m4a
but the output is mostly silent, with some random noise.
The question is how can a wav file like this : https://drive.google.com/open?id=0B9YVh-jkOMLsQThERlI2emN2QWM be converted to an audio format using a raspberry pi that can be played in the browser ?
