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


What are the frequency-curves of the iPad and iPhone (family) built-in speakers? Is there a way to hook up an iPad or iPhone as a studio-speaker, or is there a plugin simulator to audition music for iOS developement in Cubase?

iPad 2, iOS 6.1

    Are you aware the iPhone is a mobile, handheld device?


    If you have a question about Cubase, you should ask them. It seems they know something about iOS apps.

    I'm not braindead. I need to use the built in speaker in the iPad and iPhone to audition music I am producing for iPad apps - without having to upload the music to the iOS unit every time I need to reference.


    Cubase is beside the point..

    So what is the point? Do you just want to use your iPhone as a speaker?


    As for the frequency response, I don't think too many people care. It's a phone. How much bass are you going to get out of it? Is this good enough?

    1. If you don't see the point, then stop clouding my thread.


    2. If you dont care, then stop clouding my thread.

    It sounds like you expect to use the iPad as a studio reference speaker.

    It's not a studio reference speaker.

    Get a studio reference speaker.

    1. Yes

    2. Oh really

    3. I have 7


    I have a proffesional studio, and 7 reference speakers. Thats not why I'm asking. The problem is the iPads obvious inability to play lower frequencies. I need to use the iPad as a reference (with all its flaws) speaker while producing so that everything I make for the iOS app in production is possible to actually hear through the iPad speaker. It's called A/B-ing.


    It's very straight forward.

    Good luck.

    At the risk of clouding up your straightforward thread...


    1). It's an iPad

    I don't know why everyone is raining on your question, I think it is a good one. If I were a professional audio producer creating content for devices, as I authored content I would want to know how my content would sound on the devices without having to load it on each device and test it with each small change I make. For example using a production tool to simulate the frequency response of different devices based on standard profiles.


    I am sure you plan some level of final testing on the actual devices, but it would be a big time-saver to simulate the device audio profile during incremental content authoring.


    This could improve the end-user experience because you could more easily adjust the content for different device types. Doing that would be very time-consuming if you had to load the audio on a device each time you tweaked something.


    I don't have an answer for you. A poor-man's solution would be to have your production tool publish the audio content to a web server with each build. You would then have to pick up a device, browse that web site, and start the audio. Not very friendly if you are currently focusing on 5 seconds of a 3-minute track.

    I'm sorry if I'm posting in the wrong forum or what not.. I can't take this seriously anymore. For the last time - as I would explain it to a kid:


    If you were to make music for an iPad app. An iOS app for resale in iTunes (where else?). Say it's an app that will be used with headphones 10% and with the built in speaker 90% of the time. A sub bass would not be carried sonically (meaning you can't hear it) through the built-in iPad speaker. If the sub-bass part is the only bass part - you're screwed. You would then have to go back to the studio and make a new bass part to make sure the bass-line is audible when you play the music in the app. So, you would obviously check the music on an iPad before you lauched the app. Instead of checking the music the day before launch, I'd like to check it every hour while composing, and make quick ajustments.


    How to do this:


    1. I could render the music-file and upload it to my iPad to check how it sounded; This takes too much time for me, and destroys my workflow.

    2. I could use a guitar-app in "straight through" mode, and plug it with mini-jack-XLR to my monitor controller. Not sure how "straight through" it would be, and that worries me.

    3. I could stream from my workstation to my iPad over WiFi. This means compression, but perhaps not a too bad result.

    4. I could get a broken down iPad, disect it, and actually build a standalone "iPad speaker" with it's own amp.

    5. Or I could ask someone on and hope someone has a similar workflow - and a solution

    The only frequency response information you are going to find is something developed in an ideal environment. The iPad is a mobile device. The sound it is going to output is based primarily on the surface it is stitting on or the way you are holding it. The sound from a disassembled iPad speaker is going to be completely different from a functioning iPad. Do you really think there is some magic setting that is going to turn an iPad into Surround Sound?


    No one is going to have any workflow that makes an iPad sound like anything other than an iPad. I have already provided links to the information you are looking for and to apps that do what you ask. What more do you want?

    Tech Notes: iPad Audio Specifications


    Does anybody know the frequency range of the built-in microphone of an ipad 2?


    FuzzMeasure Pro 3

    and on and on.


    Note the last two are actually programs to turn your mac into a signal processing device so you can make the measurements yourself

  • cugnai Level 1 Level 1

    Llessur999 explains it well. I'm still looking for a solution.

  • Frank Caggiano Level 7 Level 7

    Did you bother to look at any of the links I posted?


    Thought your question was serious, guess not.
