Well, I guess I'll leave this post up in case anyone else is having the same problem, but it turns out I'm just dumb and didn't try changing the one setting that was causing the issue :D

For whatever reason, filtering it through the sample rate converter, even if it was set to the same sample rate as the original file, massively increased the bitrate. I took out the filter and all of a sudden I have 900kbps, 48khz ALAC files. Fascinating.


The RPA-SPDIF module is an Analog-to-Digital converter designed for use with an RP4.2-HY11 or RP4.2-HY12 interface to replace the factory Hyundai radio with a more advanced aftermarket head unit. The module converts analog audio from an aftermarket radio into a digital signal for proper audio through the factory amplifier. The module uses a high-quality Wolfson digital to analog converter (DAC) to ensure excellent sound quality.

What kind of IR detector and converter circuit could be used to down-convert an IR remote signal (in the neighborhood of 35 to 45 kHz) into audio frequency signals (0.1-20 kHz) of the appropriate level and drive to feed the mic input on a mobile phone TRRS headset jack for further analysis and decoding? Would something simply involving a divide-by-4 cascade of two D flops work? Or would decoder/(re)encoder chips or a microcontroller chip be necessary?


The 36kHz is the carrier frequency, the baseband signal is well within the audio range. Use an integrated RC receiver, it would be silly to make your own. They combine AGC, bandpass filter and demodulator.


That's well within the audio band, including quite some harmonics, so low-pass filtering it at 20kHz, or even 10, doesn't harm the signal's integrity, and you'll be able to detect edges. The image shows an 889\$\mu\$s pulse plus ditto pause, giving the higher frequency of 562Hz, cut off at 10kHz.


Mobile phone voice bandwidth is limited to 4kHz, however, and since the microphone input is primarily meant for voice input that limit may apply already here. You can play MP3 quality audio with it, but I don't know if you can record it as well. Anyway, with a worst case brick wall filter at 4kHz that same signal will look like this:


If no (so, you just want to decode IR signals using the mic input of any device, and you don't need that mapping), just use an integrated IR receiver, such as a Sharp GP1UX310QS, connect a pull-down resistor from its output to ground (to form, together with its internal \$100\;k\Omega\$ pull-up resistor, a resistor divider, that will bring its output voltage (in the order of 3 V) down to an appropriate level for your mic input -with a max amplitude in the range 10 mV to 150 mV, depending on the sensitivity), and finally connect the output also to the mic input. For instance, RC-5 encoding will give you Manchester-encoded bursts with a frequency between 281 Hz and 562 Hz (which lie inside the audio band), repeated with a frequency of 8.8 Hz (which does not lie in the audio band, but it doesn't matter, because you will still be able to see the 281 Hz to 562 Hz bursts), and which can be sampled and decoded by your phone (assuming that the frequency response of your mic input goes down to 281 Hz, which might not be the case).


In professional broadcast, post and live production workflows, the audio is just as important as the video. Blackmagic Mini Converters maintain the cleanest possible audio signal and always keep it in sync with your video! Mini Converters support embedded SDI and HDMI audio, and there are several models that let you separately embed or de-embed it to balanced analog or AES/EBU digital connections. Mini Converters support 24 bit analog and AES/EBU audio, and feature standard 1/4 inch audio jacks so you don't need custom cables!






Mini Converter SDI to HDMI 6G also includes a full 33 point 3D lookup table for high precision color conversions. You can apply custom looks, color and gamma changes in realtime for on set monitoring. LUTs can also be used with the SDI loop output, turning the converter into a 3D LUT processor! The LUTs are compatible with DaVinci Resolve so you get consistent color on set and in post!


Benchmark's DAC1 and DAC2 D/A converter families have been the reference to which other converters have been compared. It is rare to find a converter review that does not draw comparisons to the DAC1 or the DAC2. Benchmark converters are in daily use at many of the world's finest recording studios and mastering rooms. Benchmark converters are also enjoyed by thousands of audiophiles. Benchmark has raised the bar again ... the DAC3 defines a new reference.


Internal digital processing and conversion is 32-bits, and this processing includes 3.5 dB of headroom above 0 dBFS. This headroom prevents the DSP overloads that commonly occur in other D/A converters.


Benchmark DAC1, DAC2, and DAC3 converters are designed to directly drive power amplifiers and speakers. Benchmark converters feature adjustable low-impedance passive attenuators at the XLR outputs that can be used to optimize the interface to the power amplifier (or powered monitor). This unique Benchmark feature optimizes the gain staging between the DAC and the power amplifier. Proper gain staging cannot be overemphasized. When audio stages are properly matched, each component in the audio chain is able to operate at its optimum signal level, and the system performance is significantly improved.


All Benchmark converters are designed for maximum transparency. This transparency is absolutely essential in the studio monitoring chain. For this reason, DAC3 converters are ideal for critical reference-quality professional systems. Unlike many competing products, the DAC3 is not designed to add "euphonic" coloration to the audio. Instead it is designed to be as uncolored and natural as possible.


When Benchmark's professional converters are used in hi-fi applications, studio-quality sound can be enjoyed in a home environment. Enjoy pure music without any coloration from the electronics. Hear the music exactly the way it was heard in the studio, and exactly the way the artists intended.


The ES9028PRO has two distortion compensation systems that independently remove most of the 2nd and 3rd harmonic distortion in the D/A converter. Benchmark's ultra-clean analog output stages allow these systems to be fully leveraged in the DAC3. To the best of our knowledge, no other D/A converter has lower THD than the Benchmark DAC3.


Benchmark's unique passive output attenuators provide distortion-free gain reduction without reducing the dynamic range of the converter. The attenuators optimize the gain staging between the DAC3 and the power amplifier. This optimization is absolutely essential for maximizing the dynamic range of the entire playback system. Much of the success of the DAC1 and DAC2 converters can be attributed to the passive output attenuators. Musical details can be obscured by system noise whenever a preamplifier and power amplifier are improperly matched. The" HGC " system will make full use of your power amplifier's dynamic range. Experience new details in your favorite recordings.


All of the digital processing in the DAC3 is designed to handle signals as high as +3.5 dBFS. Most digital systems clip signals that exceed 0 dBFS. The 0 dBFS limitation seems reasonable, as 0 dBFS is the highest sinusoidal signal level that can be represented in a digital system. However, a detailed investigation of the mathematics of PCM digital systems will reveal that inter-sample peaks may reach +3.01 dBFS while individual samples never exceed 0 dBFS. These inter-sample peaks are common in commercial releases, and are of no consequence in a PCM system until they reach an interpolation process. But, for a variety of reasons, virtually all audio D/A converters use an interpolation process. The interpolation process is absolutely necessary to achieve 24-bit state-of-the art conversion performance. Unfortunately, inter-sample peaks exceeding 0 dBFS cause clipping in most interpolators. This clipping produces distortion products that are non-harmonic and non-musical . We believe these broadband distortion products often add a harshness or false high-frequency sparkle to digital reproduction. The DAC3 avoids these problems by maintaining at least 3.5 dB of headroom in the entire conversion system. We believe this added headroom is a groundbreaking improvement.


Benchmark's USB system supports USB Audio 2.0, DSD, and USB Audio 1.1. It is frequency agile, and will follow sample rate changes initiated by the computer and/or the media playback software. In all modes the USB communications are asynchronous in order to eliminate unnecessary sources of jitter.



The DAC3 has a low-jitter master clock which controls the transfer of audio data from the computer to the USB sub-system. The computer asynchronously transfers audio data to a buffer in the DAC3. The contents of the buffer are then asynchronously transferred to the D/A conversion subsystem. This second asynchronous transfer eliminates any traces of jitter that accumulate as the data is transferred between the USB and conversion subsystems. No traces of jitter-induced distortion are measurable to our measurement limits (better than -150 dBFS). This truly represents the state-of-the art. Enjoy the convenience of computer playback without compromise. The Asynchronous USB system supports USB Audio 2.0 for high-resolution 192kHz, and DSD playback. No drivers are required for MAC operating systems. An easy-to-install driver adds 192 kHz and DSD capabilities to Windows operating systems.



An asynchronous, driverless USB Audio 1.1 mode supports sample rates up to 96 kHz. This USB mode can be selected from the front panel or from the remote control. The driverless USB Audio 1.1 mode allows quick plug-and-play connections to Windows, MAC, iOS, and Linux operating systems without installing drivers. Just plug in the USB, and the DAC3 becomes an available audio device.



The USB subsystem remains active when the DAC3 is powered down. This prevents interruptions to the computer playback operations and eliminates the need to reconfigure the computer every time the converter is turned on.
