Help Needed With ArduboyTones [Solved]

Help & Information
#1

When I use the ArduboyTones library and try to play sounds in high frequencies, the sound turns very low. And I cannot see why. On the other hand, ArduboyPlayTunes seems to work very well.

Any help will be appreciated.

Thanks

#2

Maybe @MLXXXp can assist.

#3

Got any code to demonstrate the problem?

#4

As stated in the Readme, the maximum frequency supported by ArduboyTones is 32767 Hz. What frequencies are you trying to play?

#5

The maximum audible tone to the human ear is 20kHz so it should cover all the frequencys needed with 30kHz

#6

I am trying to play sounds with frequencies under 32767 Hz - specifically the notes included in the library(NOTE_C0 ~ NOTE_B9).

#7

This is my code:

// Sequencer
// Siwoo Kim

#include <Arduboy2.h>
#include <ArduboyTones.h>

Arduboy2 arduboy;
ArduboyTones sound(arduboy.audio.enabled);

const uint8_t scoresize = 10;
uint8_t notes[71] = {
  NOTE_REST,NOTE_C0,NOTE_D0,NOTE_E0,NOTE_F0,NOTE_G0,NOTE_A0,NOTE_B0,
  NOTE_C1,NOTE_D1,NOTE_E1,NOTE_F1,NOTE_G1,NOTE_A1,NOTE_B1,
  NOTE_C2,NOTE_D2,NOTE_E2,NOTE_F2,NOTE_G2,NOTE_A2,NOTE_B2,
  NOTE_C3,NOTE_D3,NOTE_E3,NOTE_F3,NOTE_G3,NOTE_A3,NOTE_B3,
  NOTE_C4,NOTE_D4,NOTE_E4,NOTE_F4,NOTE_G4,NOTE_A4,NOTE_B4,
  NOTE_C5,NOTE_D5,NOTE_E5,NOTE_F5,NOTE_G5,NOTE_A5,NOTE_B5,
  NOTE_C6,NOTE_D6,NOTE_E6,NOTE_F6,NOTE_G6,NOTE_A6,NOTE_B6,
  NOTE_C7,NOTE_D7,NOTE_E7,NOTE_F7,NOTE_G7,NOTE_A7,NOTE_B7,
  NOTE_C8,NOTE_D8,NOTE_E8,NOTE_F8,NOTE_G8,NOTE_A8,NOTE_B8,
  NOTE_C9,NOTE_D9,NOTE_E9,NOTE_F9,NOTE_G9,NOTE_A9,NOTE_B9
};
uint8_t score[scoresize];

void setup() {
  // Initialization
  arduboy.begin();

  // Turn on audio
  arduboy.audio.on();
}

void loop() {
  // Clear screen
  arduboy.clear();

  for(uint8_t n=0;n<71;n++) {
    sound.tone(notes[n]);
    delay(1000);
  }
  
  // Display
  arduboy.display();
}

Your array is of type uint8_t which are 8 bits long. ArduboyTones expects 16 bit values (unsigned int or uint16_t)

Change your array to
uint16_t notes[71] = {

Thanks! It worked :grinning:

Now off to making a program…
