wnb-slicer

wnb-slicer is a tool that addressed to help in custom sound preparation process for your Ninebot Zxx series EUC. Before use it you should prepare sound samples which meet the following requirements:

• the file size is not bigger than 32766 bytes, multiple sequenced sounds still not supported if it is not fit in standard EUC sound mapping scheme
• sound should be encoded as 16000Hz sample rate and signed 16bit PCM
• one second of 16Khz/16bit give us 32000 bytes of data, it is common Ninebot Zxx sounds duration (except warning sounds, it could be 2 seconds long)
• Magic

TODO

• resampling in place from wav
• maybe a simple GUI
