iPad built-in speaker frequency profile

I currently use an app called RemoteSound to stream audio from my DAW (Windows machine, actually) directly to my i devices over Wi-Fi. There's some latency, and it doesn't work with my ASIO stuff, but I can roughly preview the sound from Sound Forge and other apps I use for mastering and editing my assets. So... yeah. With RemoteSound, I kind of have my ipad standing up on its smartcover, functioning roughly like a reference speaker between my proper reference monitors.

I haven't tried it with my Macbook as my work environment is all Wintel, but perhaps this could be useful.

Cugnai,

Glad to see you read my response and found at least a little of what I wrote useful. However I think you are a bit harsh saying it was off topic! Partially answered only, yes, as I did not address the subsequent questions, and I had added information I thought you might find useful, associated to the problem presented.😮

You had said originally:

"Regarding composing, mixing and mastering music for iOS app developement.

What are the frequency-curves of the iPad and iPhone (family) built-in speakers?"

As this is not available the pragmatic an practical approach is the next best thing unless you are going to do it yourself in an anechoic chamber (or pay for it to be done) That obviously would give you a reference curve in those conditions.

You further wrote in response to another post:

"I need to know what's lost when full spectrum audio is transmitted via the built-in speaker. What the human ear picks up." and what I was suggesting is a way to do that for yourself. Perhaps not what you want to do; it is the next best approach; but NOT off topic, eh? However you have now introduced "What the human ear picks up." so let's forget the chamber idea.

I was not trying to teach you to suck eggs and from what you tell us you should know what practically can be done to achieve your aim - it is perfectly obvious the response curve does not seem to be available so other approaches need to be put into practice. You tell us you have been doing that work for 25 years. I have only been doing it for 40 years 😉. If you have the capability then what you hear and for comparison next to your reference speakers, and adjusting for that, is the best way to get excellent results. The best transducers after all, irrespective of response or corrections applied need to sound good or it is just a waste. ooops eggs suck you, again!

"Is there a way to hook up an iPad or iPhone as a studio-speaker" was the start of your second question. I assume as you have tried real time writing to and reading from a web page so I'll bypass that, never to be mentioned again.

It does seem that you have just been finding fault with all the suggestions people have made calling it 'clouding your thread' or 'off topic'. You will get the odd poster that is not helpful or misses the point unintentionally or by intent but I humbly suggest that is very poor ettiquette to reply as you do at times in this thread and you should not be surprised if posters feel aggrieved and do not help you.

I'll not cloud you any more trying to produce studio quality ipod output from a chain of equipment with no lag...............Have you tried a biscuit tin and string? oops off topic now! 😁

Sorry my bad english, but hope U'll understand the idea.. I see at the moment one way to do that. Every device has own freq response map. So what U'll is to copy that spectrum map. There is a plugin called Curve EQ from Voxengo. U probably know it. It allows you to draw complex eq curves. Also it has a possibility to adjust the opasity of plugin window and resize that window. U can find Ipad spekers freq response as a picture on web, adjust size and scale of your eq plugin window, set opacity to 50%, so you can see the original pic behind. And then just draw with mouse and copy that pic behind. When it'll done, just put it on master channel and preview what it sounds like. Maybe it's not ideal, but I think result will be very near your goal.

Cheers

I stumbled across this topic looking for something unrelated and I found it rather humorous that you somehow didn't make your own frequency response plot, being a professional audio producer apparently, in 8 months seeing how crucial this information is.

Knowing the actual frequency response of the speaker is arbitrary, as one of the well known flaws of it is that it aims at nothing, out of the back of the device. Are you using a reflector? Is your official case folded behind it, which reflects forward? Both of those change the "frequency response" of the speaker.

So even if you had a perfect plot of what the speaker did, what exactly are you going to do, EQ your audio tracks differently? Without dictating the listening environment and reflections out of the speakers, it doesn't matter.

And further, anyone who actually cares about sound on an iPad uses better headphones or speakers, so developing for the obviously limited and midrange scooped iPad default speaker that is pointed nowhere and further diminished by poor placement is ridiculous, no different than developing for the actual apple headphones.

Finally, I'm not exactly sure how you don't have a workflow for a device that includes rapid prototyping for that device. You'd obviously want to demo everything even if you applied some sort of "time saving EQ template" to it.

Is it really that difficult to output reference patterns to see what attenuation and reinforcement is happening one time to craft a chart? Time waste regardless because if you moved a reference microphone to any number of potential typical listening papositions the curves would be completely different.

Or is your plan to make the best mix for someone holding the speaker pointed away from them AND two inches above their lap, magically? because you! with your gear and experience should know, in that case you create accurate audio so no single listening environment is favored intentionally.

Hey, have you tried playing one of those speaker frequency range test videos on your device? I used this one to determine what frequencies are best heard on my iPad2. It helped me a lot and I hope it helps for you too.

Cugnai, this is a perfectly good question. I am making a ringtone specifically for the iPhone, and I needed a way to output the sound from Logic to the iPhone (like an audio out going through the iPhone) so that I could hear exactly how it was going to sound on the iPhone while I was producing it in Logic.

Airfoil for Mac was the best I could come up with. It wirelessly sends audio from you Mac to your iPhone. There's about a 3 second lag, but it's better than nothing.

First download Airfoil onto your computer: https://www.rogueamoeba.com/airfoil/

Get the app "Airfoil Speekers Touch" from the App Store.

After you install the software on both your computer and your iPhone you choose the application that you want Airfoil to pull the audio from. And that's it, it works pretty good. To take it a step further, have you ever used Soundflower as an audio out? If so, that's an easy way to do it. Set you computer out to Soundflower, and then no matter what program you're working in the computer's output will go through Soundflower, then to Airfoil, then to your iPhone.

i completely understand your question, btw and need the same information - interesting that it's so hard to find -

I found this thread while looking for the same solution. I eventually discovered this which should be exactly what you're looking for! It is a speaker built around an actual mobile phone speaker so you ca reliably mix and reference your work on mobile in realtime.
