Hi to all,

I started to develop a STM32F4-Discovery Soft Synth. A video showing it's first  beta release is here:

In some post I view a interest to audio application using STM32F4-Discovery.

Can someone that have interest in audio processing  give me some suggestion for the next release ? What kind of features to add ?

Dear Alessandro,

For my hobbies, I plan to create some electronic instruments based on stm32f4 discovery board.

You said your project will be released as open source. So is it possible to send me your dev file.

For my project I will use some wavetable with postprocessoring to change the sound effect.

I will be very gratefull if you will share your work.

King Regards.

Christophe

I'm not sure whether your interests extend to recording, but what about developing the audio recording example on the F4 Discovery? The example program (I have found) records with extraordinarily poor audio quality - surprisingly since the specs of the components suggest it should be able to get good results. You might like to try to find out the reasons for this and develop a proper audio application that can record in good quality. Features to include could be: automatic handling of file names without overwriting existing files; simple push-button to start recording; options for recording level and bandwidth/file format; better handling of the file system and FAT32; RTC; LCD etc.
