iPad Audio Input Options
It turns out that in some ways, getting audio signals into the iPad is similar to getting audio signals into the iPhone 3GS, and in some ways it’s not.

SignalScope on iPad?
The question frequently comes up, whether the existing Faber iPhone apps, SignalScope/Pro, SoundMeter, SignalSuite, etc will work on the iPad. The answer is, yes, they all work on the iPad. They aren’t universal apps, which means that they either appear in a small window in the middle of the iPad screen, or they can be zoomed to (mostly) fill the large screen. Even though the graphics are not as crisp when the apps are zoomed, these apps still offer a good user experience on the iPad.

Faber Acoustical is pleased to announce that SpeakerDraft 1.2 is now available for download on the iTunes App Store. Version 1.2 brings a few important enhancements, as well as compatibility with the iPhone and iPod touch. New in version 1.2: SpeakerDraft now runs on all iPhone OS devices, including the iPhone and iPad Driver properties now include nominal diameter (in inches), nominal impedance, and mounting depth. Box dimensions are constrained by the size of the driver (you can’t make a box that’s too small for the selected driver). Port dimensions are constrained by the size of the box. Some cosmetic issues have been corrected in the iPad version. SpeakerDraft 1.2 also brings with it a new, lower price. Happy subwoofer […]

Faber Acoustical, LLC announced today that SignalScope 2.0 for iPhone and iPod touch devices is available for immediate download on the iTunes App Store. With version 2, SignalScope users can now enjoy the full features of the Pro version without having to pay full price for SignalScope Pro. Faber Acoustical’s SignalScope 2.0 includes full and partial upgrades, via in-app purchase, that unlock additional tools and functionality, which previously were only available in the Pro version. In addition to enabling users to upgrade to the full functionality of SignalScope Pro for iPhone all at once, SignalScope 2.0 offers incremental upgrades. Available upgrades include individual tools, such as the level meter (functionally equivalent to the sound level meter tool in the popular […]

Today, a new video, Measuring Loudspeaker Impedance with IOScope, was published on this site, as well as on the Faber Acoustical YouTube channel. The video is both a demonstration of IOScope, as well as a simple tutorial on measuring loudspeaker impedance. Although the video is largely self-explanatory, I thought it would be beneficial to include some further explanation and tips for those who are interested. The movie is essentially broken into four chapters and a similar format will be followed here. What is impedance? How is it measured? By a generalized version of Ohm’s law, we understand that voltage is equal to the product of electrical current and impedance. This means that electrical impedance is equal to the ratio of […]
» Read moreiPhone Microphone Frequency Response Comparison
With the advent of sound level meter apps for the iPhone OS (of which SoundMeter was the first) people began to ask, “How flat is the frequency response of the iPhone’s microphone?” Early testing indicated that the built-in microphone of the original iPhone was not a good candidate for sound level measurements, but that the iPhone’s headset microphone enjoyed a fairly flat response. Since then, additional iPhone models have arrived on the scene, each with its own set of weaknesses with respect to microphone frequency response. Additional Apple and third party headset microphones have also been introduced. At long last, some relevant frequency response measurements are presented here for the benefit of those who would really like to “see” how […]
» Read moreiPhone Line Input Frequency Response Comparison
Although I already listed some options for getting line-level audio into an iPhone or iPod touch, that list didn’t include much information that would suggest which option would be best. One important metric that people frequency ask about is frequency response. Well, I finally have some frequency response comparisons available to help answer that question. These measurements were made of various dock connector devices, attached to an iPhone 3GS. As in other frequency response measurements, the audio was routed through the iPhone, with a little help from SignalScope Pro. This means that each measurement includes the frequency response of the iPhone 3GS headphone output. The tested devices include: Tunewear Stereo Sound Recorder for iPod Alesis ProTrack Griffin iTalk Pro MacAlly […]
» Read moreiPhone Dock and Headset IO Frequency Response
People often ask about the frequency response of iPhone and iPod touch audio inputs. To shed some light on the issue, I made some frequency response measurements of the iPhone, iPhone 3G, iPhone 3GS, and iPod touch 2G with Electroacoustics Toolbox and an Edirol FA-101 audio interface. These measurements are broken into two groups, one for headset input and one for dock connector input. Since measurements were made by routing audio through each iPhone OS device (by way of the Audio Play Through function built-in to SignalScope/Pro), all measurements include the frequency response of the headphone output in addition to the response of the selected input. The frequency response of the Edirol FA-101 was removed from the measurement, using a […]
