All are claims that are worthy of some scrutiny beyond blind acceptance of big numbers. The and kbps bit rates are about as good as CD quality, but quickly lose fidelity above 20kHz. Smartphones rarely pick the kbps option when connecting to LDAC equipment. Frequency response up to 96kHz?

    If you want to configure these settings yourself, you can find them in the Developer Settings of your Android smartphone. Here are the results: Data collected by Robert Triggs. First the good news: The kbps setting works as advertised. The codec transmits audio right up to 47kHz before slowly rolling off, granting it Hi-Res status. Both codecs roll-off at With a very steep, high ripple filter occurring just before 18kHz. When testing aptX and regular SBC we found that these codecs extend right the way up to 19kHz before beginning a smooth roll-off, reaching just -6dB at 20kHz.

    Noise floor and distortion Frequency response is just one part of the quality equation and technically anything around 20kHz is good enough to match human perception. For example, a CD contains 16 bits of data. Hi-Res bit offers far less noise, and dB is the practical limit for even the best recording devices. For starters, kbps clearly does raise the noise floor compared with the full bit Hi-Res dB target, but not linearly.

    The noise floor appears to go as low as dB below Hz before clocking in at around a very respectable dB right up until about 15kHz, making this better than what we might expect from even a dithered CD.

    We can also note that the noise floor increases at high frequencies above 15kHz, reaching highs of dB. Did you spot that the noise floor seems to fall again after the last spike?

    The kbps encoded signal is clearly noisier at low frequencies and the noise floor starts to increase a little sooner. Data collected by Robert Triggs. The noise floor increases substantially to a not-unreasonable dB at low frequencies, hitting dB between 1kHz and 5kHz, dB around 10kHz.

    At 15kHz the result peaks at dB, which will definitely interfere with the high-frequency presentation. Regular Bluetooth SBC is nowhere near this bad, and this is by far the worst high-frequency performance I have seen from any Bluetooth codec.

    A second test throwing more high-frequency harmonics into the mix seems to stimulate LDAC into action above 20kHz.

    Blue: LDAC kbps. We see that the noise floor increases even further at higher frequencies. For kbps, the results again appear very similar. The noise floor creeps up more much noticeably for high frequencies above 15kHz, and is certainly worse than CD quality here. It's much better as a CD quality codec—except for the kbps setting which is poor by all measured criteria. The story is much the same as with Hi-Res, but the noise floors for and kbps are slightly worse here because of the limits of our bit test files.

    Again the kbps shows a notable increase in the noise floor above 10kHz, starting at dB and reaching dB near cut-off.

    LDAC kbps comes out ahead at most frequencies tested, but the latter manages to keep its very high-frequency noise floor lower. The noise floor profile fits into the same margin of error, stuck in the region of dB for low frequencies, dB in the mids, and as high as dB near the cut-off frequency. It performs worse than aptX and regular Bluetooth SBC at all frequencies, yet all use similar bandwidths.

    LDAC is only as good as its connection strength A quality Bluetooth codec is only as good as its connection strength. The important question is what can consumers actually experience in the real world.

    Print The sound of our mobile phone is not exactly one of the facets in which manufacturers strive the most, especially if we talk about mid-range or entry-level mobiles And many times it seems that they do not do it simply due to reluctance or lack of time and resources. Today we tell you how easy it is to improve the sound of the mobile with Qualcomm processor thanks to a module for Magisk Manager, one of the most popular tools today to root.

    There are many ways to improve the sound of a android phone, and in many cases specific for a certain type of mobile, a specific brand or a specific processor like the one we know today. Improve the sound on your Android without installing any app Improve mobile sound with Magisk Today we echo a new module for Magisk Manager That allows us to greatly improve the sound of a mobile that has a Qualcomm processor.

    All these processors share an architecture that can be used by this module to improve that sound. This common element is the integrated Wcd9xx audio DAC, which has a series of parameters that can be activated and deactivated to modify some settings.

    This specific module enables high performance mode of the DAC of our phone to maximize power to offer us the best possible audio quality. The requirements to be able to enjoy this module are very clear, on the one hand, as it is obvious, to have a mobile that has a Qualcomm processor, as well as to have the Magisk Manager installed in its version With these two requirements we can install this module and enjoy better sound on our mobile with Qualcomm processor.

    We just have to download the following files. Obviously, we must be cautious when using this new module and not trust ourselves too much when it comes to increasing the power and volume in the mobile, it is better to do it gradually, especially so as not to damage the speakers with excessive volume. In any case, normal use will allow us to enjoy, in short, a higher quality sound on our phone with a Qualcomm processor. To report an error click here!

    Any custom recovery will do, however.

    Enjoy a better Sound Quality with Hi-Performance DAC Enabler

    Reboot your phone into recovery mode. Different devices have different button combinations to access recovery mode, however, on some devices, this can be done right from the software. Once enabled, go to Developer options and enable Advanced reboot if available. The next time you press reboot on the power menu, you will be presented with a few options. One of these would be reboot to recovery. This is an optional step, but we highly recommend that you do this.

    There is no guarantee the mod will successfully install on your device.
