Wav files played form an atmega

I am pretty sure that's not the case as the whole point of the project is to read large CD quality wav files from SD card. I have contact to him now and he says that it's a tricky one, getting 16 bit stereo and that the quality doesn't differ a lot from 8 bit but I am quite persistent We went thru all this 'audibility of digital quantization' in the early 70s.

Live sound and wide dynamic range need more bits. The early ensonique synths were 8 bit, but by the time one added 6 or 8 waves together, it was running out of headroom. Engineers are usually somewhat conservative cheap , and I think that the ads touting more bits and faster sampling was marketing.

I dont see any sense in recording something at 24bit 96KHz, then putting it on a CD at 16 bit and I'd like to see the AB compare of those 2 wav formats against a kbps mp3. Something like a bass line with brush cymbals 20db down.

That violates the psycoacoustic 'rules' that the mp3 algo uses to throw out spectra that are inaudible. I predict the brushes would be thrown out, thus converting a jazz duo to a solo. Until you start mixing and mastering. Playback environment makes a big difference as well. A big-screen theatre's sound system is somewhat different from a teenager's eye-pod. If you're recording straight from the floor and are doing little or no post-production, sure it's overkill.

May I repeat my request for suggestions for a more powerful MCU that would be capable of doing both tasks and is available either in DIP format or on a small breakout board.

But I have not yet done any testing today. If there is not a more powerful small and cheap MCU then it may be simpler just to use a second dedicated to the sound. Keep in mind also that it will be necessary to select from several sound files in a seemless fashion.

You can email the supplier to ask the exact size. Contact them to see if they have a reflow oven. If so, they can solder all 10 at once, probably for the cost of a couple of pints for the operator.

It's hard to say what are the limits to the size.

Long and thin might fit in one space and a more "square" footprint might fit another space. The DIP chip is about 35mm long and that is almost too long. The third dimension height also needs to be as small as possible - 3mm is a lot.

Have you considered a dedicated WAV player module like this. It seems quite small and has an SD card slot for your sounds built in. It looks like it can be controlled using serial or simulated button presses and people have done write-ups on it's use from arduino here and here.

Thanks Riva , that WAV player looks interesting. However I don't think I have the patience to order it from Hong Kong.
