Audio Codecs toy the most significant role in the wireless audio experience as well as latency . If you are using expensive radio earphones likeBose QC 35 , it is extremely important that they run at the good Audio Codec potential . amazingly the company do n’t play cool when it comes to displaying and customizing Bluetooth codecs .
For example , Windows does n’t permit you choose the audio codec and neither evidence you whether it ’s running on aptX or SBC . For iPhone , I had to connect it to a MacBook and then monitor the cabinet to figure out that the Apple Earpods run on AAC ( Advanced Audio Codec ) . No way to customise or view the codecs usable . So with the remaining macOS , Android , and Ubuntu , there is a workaround to vary Bluetooth audio codec .
Best Bluetooth Audio Codec: SBC, AAC or aptX
first , rent ’s understand what is a codec and which is the best one to habituate . A codec is a unretentive form ofCoding andDecoding . In case of wireless earphones , the audio signal is coded and then send to the earphones where it is decoded . The hero - equation or default Bluetooth codec is SBC ( SubBand Codec ) . It has a hefty lossy speech sound condensation , less - office consumption , and noticeable rotational latency . Latest Codecs like aptX and AAC are almost lossless and has relatively less latency .
For a twist to ladder on AAC or aptX , both the audio twist and operating system must stomach the codec . All the Operating organization do support aptX and AAC . So , if yourBluetooth headphones / phone keep aptXor AAC mostly the OS will run it on that codec . But at time the OS does n’t recognize the audio gimmick and runs it at SBC . In fact , the OS frequently tend it on SBC on design to preserve shelling and mastery CPU thermals . However , there are shipway to impel the group O to use better Bluetooth codecs and get the sound audio character all the time .
get ’s see how to force the twist to use the best codec .
1. Android
The most straight forward method acting is in Android . Android equipment are aptX and AAC compatible and will operate at highest codec if your headphones are compatible . To push or vary the Bluetooth codec first , you have to link up the headphones to your Android gadget . Next , start take on a Sung on your phone because this is the time the codec gets participating . After that , lead over to the preferences bill of fare and move toDeveloper Options . If you do n’t see Developer option in your Android preferences , here is aguideto enable it .

In the Developer pick bill of fare , navigate to the Networking section and tap on“Bluetooth sound recording codec ” . Here , you will have different audio codecs to opt from . The affair with Bluetooth audio codecs is that both the equipment postulate to support the codec else no sound will be played . By default , the unspoilt audio codec will be pick out . In pillow slip it is still on SBC , you may shift to AAC or aptX , whatever your earpiece documentation .
Android also provides other customizations for audio likeBluetooth audio sample rateorBluetooth Audio Bits Per Sample . you may alter these configurations but check that that your headphones patronage the particular sampling rate and bit streaming .
instead , when your Bluetooth headset connect , go to Bluetooth background and snap on the headset ’s configurations icon . If any other codec by from SBC is uncommitted , Android will mechanically show an useable toggle for that finical codec .
2. macOS
The approaching in macOS is not as straight - forward as Android . Qualcomm aptX HD is supported on macOS ( blue iPhone users ) but Apple does n’t allow you to storm or exchange it . macOS tends to flip to SBC to save battery and manage thermals . But , there is a way to force macOS to habituate aptX or AAC all the time . For that first , you need to download theAdditional Tools for XCodefrom the Apple Developer Website . If you have n’t registered on thesite , you may do it for free * thankfully * .
If you are on mac Seirra , Additional Tools for Xcode 8 will work .
Once you have the XCode tools downloaded , twofold - select it and afford the brochure . Navigate to the “ Hardware ” folder and you will retrieve Bluetooth Explorer.app . Drag and drop this to the Applications folder .
Once you set the Bluetooth Explorer app in the Applications folder , you’re able to now get at additional audio options . Double tap Bluetooth Explorer and then click onToolson the Menu ginmill at the top . Next , get across onAudio Optionsfrom the elongated menu .
From the Audio Options dialogue boxful , check“Force use of aptX”and“Enable AAC ” . Make certain you uncheck “ Disable aptX ” and “ Disable AAC ” as these alternative incapacitate both the Bluetooth codecs .
After you have enable aptX or AAC , connect your aptX compatible Bluetooth earphones to the mac . Play an audio file because that only activates the Bluetooth Codec . To assert aptX is been used , hold down the Option key and select the Bluetooth ikon on the menu bar at the top - left-hand .
Under the Bluetooth carte du jour , navigate to your wireless audio gadget link and you will have a tray swoop out . The tray contains the dynamic Bluetooth Codec which should be “ aptX ” .
If audio frequency is not playing on the twist , active codec express Arkansas
