Re: Can't Get Samples to Work

[Sam Aaron]

Hi there,

this is extremely confusing!

I assume /home/noah/Downloads/stupid.wav exists on your system and is a valid wav file.

How are you starting the server internally or externally?

Could you show me the contents of:

tree ~/.overtone

The 2nd issue

Exception Unable to load sample - file does not exist: /home/noah/insane-noises/overtone.sc.sample.PlayableSample@c4dfd7f5  overtone.sc.sample/load-sample* (sample.clj:73)

is because you should (def kick ...), not (defsample kick ...), I think.

Apologies Sam, it was written sleep deprived and was not proofread. Yes, stupid.wav is a short George Carlin sample that I downloaded to test out sample functionality. I am connecting to the server internally.

Here is ~/.overtone.tree: . .. assets  config.clj  log  speech.

[saltyk...@gmail.com]

Thanks Roger. I used defsample because I read elsewhere online that that is what I needed to do.

does this imply that your assets dir is empty? When I tree ~/.overtone I get quite a long output...

whereabouts did you read this? We should probably clarify correct this.

I've just added a docstring to the defsample macro which is unfortunately absent in the latest release. It now reads:

"Define a s-name as a var in the current namespace referencing a
sample with the specified path and args.

Equivalent to:
(def s-name (sample path args...))"

Sorry I actually didn't know what you meant as I had never used the tree directory listing program before.

It was nowhere "official" and I can't find it. On the Github Wiki it is correct, but I didn't read that section until today.

[Sam Aaron]

Hi Noah,

so it looks like there are some samples cached in your ~/.overtone directory.

What's the return value when you type into the REPL:

(freesound-path 777)

I cloned a fresh copy of Overtone and samples are working, however, now I have another issue.

When I run

(defsynth foo [in-bus 0]
  (let [sig (sound-in)
        sig (pitch-shift sig 0.2 2)]
    (out 0 sig)))

my microphone works. When I run

(recording-start "~/Desktop/foo.wav")
;;make some noise...
(demo (pan2 (sin-osc)))
(recording-stop)

my it doesn't, but the sine wave is captured.

Apologies, I don't fully understand your question.

If I do the following in this sequence, I hear the foo synth and the sin-osc in the recording:

(defsynth foo [in-bus 0]
(let [sig (sound-in)
sig (pitch-shift sig 0.2 2)]
(out 0 sig)))

(recording-start "~/Desktop/foo.wav")
;;make some noise...

(foo)
(demo (pan2 (sin-osc)))
(recording-stop)
(stop)

Was this the issue, or did I misunderstand?

Ahh apologies again; I am going to make sure to check my posts better for coherence before sending them off. What I was trying to say is that when I run the first program my microphone works and the incoming sound is pitch shifted as expected. When I run the latter program, no sounds I make are recorded through the microphone. However, if I generate sound from within overtone, that sound is recorded into the .wav file it outputs.

[Sam Aaron]

Hi Noah,

Unfortunately, I still don't fully understand what you're trying to do:

"When I run the latter program, no sounds I make are recorded through the microphone."

I assume, you mean, "when I run the latter program, no sounds are recorded when I make noise into the microphone".

Could you try the following steps:

;;1. define this synth

(defsynth foo [in-bus 0]
(let [sig (sound-in)
sig (pitch-shift sig 0.2 2)]
(out 0 sig)))

;;2. start the synth
(foo)

;;3. start recording
(recording-start "~/Desktop/foo.wav")


;;4. make some noise...
(demo (pan2 (sin-osc)))

;;5. stop recording
(recording-stop)

;;6. Listen to the recording and see if you can hear any noise from the mic.

Sam
