Hallo,

i'm experimenting with AudioEffectRecord and audiogenerator.

Do i miss some sort of initializazion step? Like linking the AudioEffectRecord to the AudioStreamPlayer for example? The save produces actually no file saving at all.

#Declaration
var rec : AudioEffectRecord = null 


func _process(_delta):
	_get_input()
	_fill_buffer()


func _ready():
	rec = AudioEffectRecord.new()

	$Player.stream.mix_rate = sample_hz # Setting mix rate is only possible before play().
	playback = $Player.get_stream_playback()
	_fill_buffer() # Prefill, do before play() to avoid delay.
	$Player.play()
	
func _get_input():
	if Input.is_action_pressed("ui_up"):
		pulse_hz += 0.1
	if Input.is_action_pressed("ui_down"):
		pulse_hz -= 0.1
	if Input.is_action_pressed("ui_right"):
		pivar += 0.1
	if Input.is_action_pressed("ui_left"):
		pivar -= 0.1
	if Input.is_action_just_pressed("ui_page_up"):	
		rec.set_recording_active(true)
	if Input.is_action_just_pressed("ui_page_down"):
		#rec.set_recording_active(false)
		rec.get_recording().save_to_wav("res://1.wav")

Any hints is appreciated. P.s I've skipped other irrelevant code.

Thanks

I don't think you can save to "res://". You should probably open a file dialog to select the path.

Sorry for not updating. I've solved using the bus audio mic example, and changing the routing of the audio generator (audioplayer) to the record bus (using the appropriate index that corresponds to the record fx.

Is possible to save without dialog as well. My function func _new_file_name() create recordings named using the follogin pattern:

fname = "res://" +  str(n) + ".wav"

save path

func _get_input():
	if Input.is_action_pressed("ui_up"):
		pulse_hz += 0.01
	if Input.is_action_pressed("ui_down"):
		pulse_hz -= 0.01
	if Input.is_action_pressed("ui_right"):
		A += 0.01
	if Input.is_action_pressed("ui_left"):
		A -= 0.01
	if Input.is_action_just_pressed("ui_page_up"):	
		if  effect.is_recording_active() == false:
			effect.set_recording_active(true)	
	if Input.is_action_just_pressed("ui_page_down"):
		$Player.stream = recording
		recording = effect.get_recording()
		effect.set_recording_active(false)
		var save_path = _new_file_name()
		recording.save_to_wav(save_path)
		print("salvato in " + save_path)
		get_tree().reload_current_scene() 

func _new_file_name():
	var file2Check = File.new()
	var doFileExists = true
	var fname = ""
	var n=0
	while doFileExists:
		fname = "res://" +  str(n) + ".wav"
		doFileExists = file2Check.file_exists(fname)
		if doFileExists == false:
			return fname
		n+=1

If the documentation on saving games is anything to go by, you might need to save the audio files to user:// instead of res://, especially in exported games since res:// is read-only.

That said, I've never tried to save to res://, so it might be possible.

Ok,

it writes without problem. However i will follow your advice, to save in another folder. Another thing that seems quite strange to me is the beaviour of the audio bus effects. The order of the effects seem to change randomly every time i run the project, sometimes disabling the audio. at all

This is what is happening:

func _ready(): var idx = AudioServer.get_bus_index("ToMaster") effect = AudioServer.get_bus_effect(idx, 0)

Since the order change, the AudioServer.get_bus sometimes point to an audio effect not to Recor, indeed to other fx.

my default bus is like this:

Master----------ToMaster

no fx-------------Record -------------------Notchfiler -------------------Phaser

Speakers------Master

Sometimes happen that Record changes position, creating a logical error in this line: effect = AudioServer.get_bus_effect(idx, 0)

Btw wich picture format is allowed by the forum?

Thanks

@fono said: Btw wich picture format is allowed by the forum?

I know that .png and .jpg are supported. I think .gif is also supported. Are you having issues with uploading images? If so, does the "Add images" button work?

No it doesn't work Is there a size limit? I get the message file is not allowed.

Hmm, strange. There is a file size limit, but its like 2mb+ if I recall. We've been having issues before with images uploading, but I don't remember if we ever got it fully sorted. I'll try to take a look once I have a chance and the time!

I've got that image upload error before, usually when drag/dropping or copy/pasting an image. In those cases, I use the image upload button and it usually works. However, you might have to edit the image first (reduce dimensions or file size) if it is too big.

The capture screen i've tried to upload is 292 kb saved as jpg. Hovever for tracking the strange behaviour inside the audio bus, i should do a video capture.

Ok, png works fine. For the fx that are changing order, i've simply added another bus before for the fx only. However the busses really seems to have some bugs.
