small chip to upload sound to for sonic screwdriver?

Projects General Guidance

i am new to electrical engineering i need to know if there is a small chip that can hold sound files such as mp3
and i also want it to be able to connect to an ATtiny85 for programming is there any chip out there? this is for a sonic screwdriver project.

Take a look at the ChipCorder series from Nuvoton. I used one way back in college when they were still part of Winbond, piece of cake for hobby projects.

Go buy a teddy bear that lets you record your own message on. There is a small chip and speaker that sounds like what you're looking for.

Go buy a teddy bear

greeting cards are available with similar functions; probably a lot cheaper than a teddy bear. Also christmas ornaments and other devices...

There are some other choices:

  • General purpose MP3/WAV playback devices like Adafruit Audio FX Mini Sound Board - WAV/OGG Trigger - 2MB Flash : ID 2342 : $14.95 : Adafruit Industries, Unique & fun DIY electronics and kits Cheaper somewhat similar modules are probably available on eBay/AliExpress/etc.
  • Similar to above, but specifically designed to connect to arduino.
  • use some fancy algorithm to load/playback a sound recording in the Tiny85. You can probably fit a (repeatable) second of sonic-screwdriver sound in the 8k of memory on the chip. Or you can add an external eeprom chip.
  • synthesize the sound using a SW algorithm. SS is probably a couple of different-frequency mixed waves, perhaps with additional modulation. There's probably published code that generates it, for some microprocessor...
