Hi , i searched internet and found our that most arduino can display only audio in terms of wav form. However, i want arduino to display a whole song (with people singing) instead of just tone, can arduino do that ?
A wav file is just a collection of instantaneous voltages that you output to a speaker. If you wanted tones eg a spectrum like a equaliser then you would need to do a fourier analysis. You could use an arduino to do an a/d and then output the voltages as a series of LED's say and the display would contain everything in the audio all at once as simple intensity values.
The shields I mentioned also come with libraries to control the music. The music is stored on an SD card as you suggested.If i store the music into sd card and just use arduino to retrieve it,do i still nid to do fourier analysis?
Yaya that is what i mean , but can i dun purchase the shield? I mean just use arduino and an sd card to achive that thing? Can?Curious, what do you mean by "display a whole song"? What are you expecting to display. If you mean play a whole song, more than just tones, there are MP3 and WAV shields that play songs recorded in those formats.
Er sry also to ask , what is the difference between wave format and mp3 format ( haha sry for asking such dumb) questionCurious, what do you mean by "display a whole song"?
