Wanted: Sound chip interfaced with pic

[xnihilo]

Decent or reasonable... that's the question
if reasonable ISD4xxx would do.

for better quality or high quality, it's obvious you really want to avoid anything like MP3... but then there's a lot of are plenty satisfied with MP3... way better than that poor noisy ISD4xxx but... you will need storage devices (MMC card or whatever else)

Worth to have a look at Winbond website, they should have better chip than those 'Telephone line' vouched ISD4002.

Hello Mister_e,

I need a sound thats not FUZZY (I mean white noise being heard when the sound is over).
Do you know what is needed (software and hardware) to use ISD chips?
Another lasergame project (Milestag, from Jim Robertson) uses a ISD 2550 but the sound is fuzzy and this chip is discontinued anyway.
Do you have an idea? MP3 with a little amplifier might do the trick, that's why I thought aout that..

Just a thought. I got a birthday card once that had a 10 second record chip in it. You know the kind when the card is opened it says something. PIC pin goes high to activate?

I do not have a part number and maybe the chips already mentioned are this.

Yes, that's what I'm thinking of. I just got one a few days ago for my birthday. It has a little speaker but the sound quality was pretty good and the chip was sunk in a black plastic so I was unable to check what chip is used. It might be a ISDchipcorder type.

I need to record my sound (or transfer it from my pc).
I need interfacing example to a PIC16F690 and PBP code.

I think Mister_e uses this kid of chips...

i need good quality audio chip

If its quality your looking for the M25P32 PIC Audio is CD mono quality for short audio(gunshot).
Record a wave of a gunshot from a video game and use the included RS232 PC to M25P32 installer in the M25P32 program.

It would require converting from Proton to PicBasicPro but their similar.

The DA outputs 16 bit 44.1K CD quality mono and all thats then required is an amp and speaker to suite.

Another options is the Quadravox QV502.

I will be posting a PIC iPOD SD card 8 bit stereo wave player later next month (Proton).

Hi,

I've already bookmarked a page related to that stuff and a post from you, intending to have a look later.
So I can interface it directly to a pic then?

[Normnet]

Interfaced directly from PIC with MSSP SPI (fastest).

I id NOT find a good interfacing example Mr SkimaskKnowsEverytging.
Yes I have the datasheet.
Yes, I am using to create a placeholder for the gunshot sound in my code but it sucks.

Funny... Google pulls up a fair amount of interfaces for me. And the VS1001 datasheet show most everything needed.

A turd... Nice...
I need a REALISTIC gunshot, that's all. Unless you have a replacement solution for such noise, your posts are somehow irrelevant... It looks like you need to have something to say to any post on this forum...

Look pal, I'm just pointing out the fact that sometimes...SOMETIMES...a person overdoes a project by a whole load and wastes a lot of money and effort for perfection when the end result doesn't justify it.

Do you know what is needed (software and hardware) to use ISD chips?

Again, Google finds a few decent examples of ISD usage with an MCU.

Do you have an idea? MP3 with a little amplifier might do the trick, that's why I thought aout that..

How much does a VS1001 cost? How much does a decent amplifier cost? How much does a decent speaker cost? How much tooling to make a good PCB? How much room in a box? Is it really viable?

I need to record my sound (or transfer it from my pc).
I need interfacing example to a PIC16F690 and PBP code.

Need need need. There are examples out there. They might not all be for exactly PICs and PBP, but they aren't that different from one to the next.

Jist of the story...how you even tried the SOUND command yet? I had a play with it a couple of days ago just to see if I was on crack, talking smack, or whatever. I think the sounds came out pretty good with the example shown in the PBP manual, nothing more. A bit more of a better filter, maybe a bit of tweaking and finding the right sound frequencies/duration, I'd think that SOUND could produce something really decent.

ISD chip could do the job, some have built-in amplifier, A DsPIC with nothing else as well

I already hard-coded some WAV sounds. A bit waste of time... but fun to do and don't require nothing else on board... just a small amplifier such as TS4962 (one of my favourite for really small size amp, really neat), opamp+transistors or this 650 years old LM386

And this also bring Roman Sound BitCoder solution. Could be fine... worth you try it.

Quadravox programmer for ISD is one solution for mass production.

For MP3, i would no longer use this about to be obsoleted VS1001, VS1011 would be a better choice.
