Sound recording on the raspberry pi Zero W - Raspberry Pi Forums

-

hello world,

started on research project in need make field recorder wifi , other sensors.

field recorder have design criteria meet:

- needs small. want build few , give them away people use several weeks. make sure not hassle them relatively small. thinking on using pi 0 w
- want capture surrounding sounds (making dynamic microphones less suitable)
- needs stereo
- needs create @ least cd quality audio

far have come understanding there 3 ways can achieve audio in on pi:
- use usb sound card or pihat (not preferable due size. furthermore, haven’t found matches pi 0 w)
- go digital tour , use mems microphones interface i2s. adafruit sells ( https://www.adafruit.com/product/3421 ) however, upon looking movie ladyada seems need shout @ close range of audio signal in; in conflict desire let people record conversations , environmental sounds
- go adc tour, opens hunt adc. latest find is: https://thepihut.com/collections/raspbe ... adc-pizero .

relatively new raspberry pi , new audio recording , hoping pointers. have experiences (and successes) methods listed above , mind share insights?

[edit]
sorry, see want wifi connection , other sensors of irrelevant.

may particularly want use raspberry pi , may prefer diy project. still, should aware of alternatives job , avoid hassles battery power, long boot times, rugged construction, simple operation etc. there lot of wheels reinvent in diy device.

jut mobile phone can record audio , has 1 them @ times. don't stereo, smartphones may support usb microphone or other audio input device in stereo. worth look.

go super cheap £2.50 voice recorder in usb memory stick.

£40 (probably close complete pi 0 solution might cost) more serious.

, there number of others @ every price point £100s

think audio quality down microphone , 1 cost more raspberry pi.

Error: ‘for’ loop initial declarations are only allowed in C99 or C11 mode - Raspberry Pi Forums

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
