This is related to a question I just asked in the "How do I..." forum.

My project needs to use mobile Bluetooth and as that is not supported by Safari I am having to use a browser called "Bluefy" (which is available for Android and iOS.)

My website/program was loading until I added a .webm sound call. Now I'm just getting a black screen. (It works on Safari - except the Bluetooth part, of course.)

I thought maybe I could use a different format, but Construct seems to automatically convert all audio files to .webm Opus.

I've written a short program that plays audio from a URL:

- Add remote URL "https://example.com/test/test.webm" (type "audio/webm; codecs=opus") as name "voice"

- Play "voice" not looping from Sounds at 0 dB (tag "voice")

I've exported this code to my website and it runs just fine on my PC. Unfortunately, I need it to work on my iPhone, too. But when I push the PLAY button nothing happens.

Any ideas?

UPDATE: I just saw this bug: "Audio remote url doesn't work in iOS #4721". Ashley says the workaround was to make sure to include .webm files in the program. All of my audio files are .webm, so I know that's not the problem.

Thanks for all the replies!

I should have been a little more specific about what I need to do. I have written a little tool that does two things:

1) It records audio from my microphone

2) It starts a timer, so when I press keys on the keypad I can save the timestamps, and the key values, in a JSON file.

I have another program that starts a timer and PLAYS the audio files. Then I can look at the JSON timestamps to "sync" the audio file with my program. I have this working already, but the audio files are Mono, and Stereo would be much better.

Is it possible to launch Audacity from Construct 3? I wonder if the timing would be a little inconsistent, though.

I want to record binaural audio so I bought a special microphone. Unfortunately, the audio recorder built into Construct appears to only be mono!

Is there any way to record stereo audio?

UPDATE: I should have been more specific in my initial question. I am looking for a way to record stereo audio using Construct 3. (Even if I have to use the Javascript feature.) It's part of a more extensive program.

I have a niche business idea that I think could do fairly well. It would involve me bundling an audio file with a data file, and selling these as "programs".

I'd like to make a really nice-looking Shopify site and sell my programs there, and then have a button or link on Shopify that takes customers to my C3 Player program... which would be on a different website. That's not ideal, but I think it should work. Anyone see issues with that approach?

Alternatively, I could create a website that includes my player program. But then I would need a shopping cart of some kind to handle the sales part. Five years ago someone mentioned using Snipcart... Has anyone tried that recently?

Okay, fixed my problem.

I was using a tag when I downloaded the sound, but not when I *played* the sound. Once I set and used that second tag it worked great!

Thanks, Jase00!

Because the audio object offers you Audio.CurrentTime or Audio.PlaybackTime(Tag) which you can compare against your timestamps.

I'm not sure if it's a bug, but apparently "Audio.PlaybackTime(Tag)" doesn't work when you load a sound externally. (Using "Add remote URL".)

Maybe I can simply use timers.

My application requires a vocal recorder. I looked at some of the code but didn't have a microphone to test it. I wound up buying a microphone that has really good stereo (it's almost binaural). Unfortunately, the audio recorder built into Construct is only mono!

Does anyone know if this is a limitation of Construct? Or is it an HTML5/browser limitation?

Haha. No, I'm not making a story book app. :-) I just came up with that as an example since it seemed easier to explain.

I'm actually trying to control a TENS machine using Bluetooth, and I want to sync signals from the machine with a long audio file that is playing.

Thanks for the reply anyway! I appreciate it!

Thanks, WackyToaster! I don't often get replies to my questions here so I appreciate the response. :-)

I'm saving the timestamps in a dictionary object and then comparing them against the current time every tick. (That's the idea anyway, haven't tried it yet.)

I hadn't found the Audio.CurrentTime or Audio.PlaybackTime(Tag) properties yet, but those sound like they should work much better. Thanks!!
