# Boîte à musique virtuelle
|
||||
|
||||
Joue simplement un son de boîte à musique pour faire croire que l'on a une boîte à musique ;-)
|
||||
|
||||
|
||||
## NodeMCU
|
||||
|
||||
Utilise la fonction PCM du NodeMCU:
|
||||
|
||||
https://nodemcu.readthedocs.io/en/master/modules/pcm/
|
||||
|
||||
|
||||
|
||||
## Source audio
|
||||
|
||||
https://youtu.be/Fr2N-5V7aqQ
|
||||
|
||||
|
||||
## Convertisseur Youtube en MP3
|
||||
|
||||
https://www.mp3hub.com
|
||||
|
||||
## Convertisseur MP3 en WAV pour pouvoir le jouer avec le NodeMCU
|
||||
|
||||
https://www.audacityteam.org/download/
|
||||
|
||||
Il faut convertir le MP3 en WAV raw 8 bits mono 1k ou 16k SpS
|
||||
|
||||
### Marche à suivre facile
|
||||
|
||||
* mettre 16000 tout en bas à gauche
|
||||
* convertir en mono (Pistes/Piste stéréo vers mono)
|
||||
* sélectionner avec la souris la partie à garder (cliquer sur le graphe !)
|
||||
* exporter la sélection (Fichier/Exporter l'audio sélectionné)
|
||||
* choisir autres formats non compressés puis btn option
|
||||
* choisir WAV Microsoft unsigned 8 bits PCM
|
||||
* enregistrer en effaçant les métas données !
|
||||
* vérifier les informations avec le finder

# Cigales virtuelles
|
||||
|
||||
Joue simplement un son de cigales pour faire croire que l'on a des cigales dans son jardin en été ;-)
|
||||
|
||||
|
||||
## NodeMCU
|
||||
|
||||
Utilise la fonction PCM du NodeMCU:

|
||||
|

## Source audio
|
||||
|

|
||||
## Convertisseur Youtube en MP3
|

## Convertisseur MP3 en WAV pour pouvoir le jouer avec le NodeMCU
|
||||
|
||||
https://www.audacityteam.org/download/
|
||||
|
||||
Il faut convertir le MP3 en WAV raw 8 bits mono 1k ou 16k SpS
|
||||
|
||||
### Marche à suivre facile
|
||||
|
||||
* mettre 16000 tout en bas à gauche
|
||||
* convertir en mono (Pistes/Piste stéréo vers mono)
|
||||
* sélectionner avec la souris la partie à garder (cliquer sur le graphe !)
|
||||
* exporter la sélection (Fichier/Exporter l'audio sélectionné)
|
||||
* choisir autres formats non compressés puis btn option
|
||||
* choisir WAV Microsoft unsigned 8 bits PCM
|
||||
* enregistrer en effaçant les métas données !
|
||||
* vérifier les informations avec le finder

Create, Edit and run NodeMCU files using your webbrowser.
|
||||
Examples:
|
||||
http://<mcu_ip>/ will list all the files in the MCU
|
||||
http://<mcu_ip>/newfile.lua displays the file on your browser
|
||||
http://<mcu_ip>/newfile.lua?edit allows to creates or edits the specified script in your browser
|
||||
http://<mcu_ip>/newfile.lua?run it will run the specified script and will show the returned value

# Player de musique
|
||||
|
||||
Joue simplement un fichier audio avec le NodeMCU, une sorte de mini player MP3 ;-)
|
||||
|
||||
Très pratique quand on doit faire des bruitage pour un projet media design
|
||||
|
||||
## NodeMCU
|
||||
|
||||
Utilise la fonction PCM du NodeMCU:
|
||||
|
||||
https://nodemcu.readthedocs.io/en/master/modules/pcm/
|
||||
|
||||
## Convertisseur Youtube en MP3
|
||||
|
||||
https://www.mp3hub.com
|
||||
|
||||
## Convertisseur MP3 en WAV pour pouvoir le jouer avec le NodeMCU
|
||||
|
||||
https://www.audacityteam.org/download/
|
||||
|
||||
Il faut convertir le MP3 en WAV raw 8 bits mono 1k ou 16k SpS
|
||||
|
||||
### Marche à suivre facile
|
||||
|
||||
* mettre 16000 tout en bas à gauche
|
||||
* convertir en mono (Pistes/Piste stéréo vers mono)
|
||||
* sélectionner avec la souris la partie à garder (cliquer sur le graphe !)
|
||||
* exporter la sélection (Fichier/Exporter l'audio sélectionné)
|
||||
* choisir autres formats non compressés puis btn option
|
||||
* choisir WAV Microsoft unsigned 8 bits PCM
|
||||
* enregistrer en effaçant les métas données !
|
||||
* vérifier les informations avec le finder
