Getting MatchError "MATCH_ATTEMPT_FAILED" everytime when matchstream on Android Studio Java+Kotlin project. My project reads the samples from the mic input using audioRecord class and sents them to the Shazamkit to matchstream. I created a kotlin class to handle to Shazamkit. The audioRecord is build to be mono and 16 bit. My Kotlin Class class ShazamKitHelper { val shazamScope = CoroutineScope(Dispatchers.IO + SupervisorJob()) lateinit var streaming_session: StreamingSession lateinit var signature: Signature lateinit var catalog: ShazamCatalog fun createStreamingSessionAsync(developerTokenProvider: DeveloperTokenProvider, readBufferSize: Int, sampleRate: AudioSampleRateInHz ): CompletableFuture<Unit>{ return CompletableFuture.supplyAsync { runBlocking { runCatching { shazamScope.launch { createStreamingSession(developerTokenProvider,readBufferSize,sampleRate) }.join() }.onFailure { throwable -> }.getOrThrow() } } } private suspend fun createStreamingSession(developerTokenProvider:DeveloperTokenProvider,readBufferSize: Int,sampleRateInHz: AudioSampleRateInHz) { catalog = ShazamKit.createShazamCatalog(developerTokenProvider) streaming_session = (ShazamKit.createStreamingSession( catalog, sampleRateInHz, readBufferSize ) as ShazamKitResult.Success).data } fun startMatching() { val audioData = sharedAudioData ?: return // Return if sharedAudioData is null CoroutineScope(Dispatchers.IO).launch { runCatching { streaming_session.matchStream(audioData.data, audioData.meaningfulLengthInBytes, audioData.timestampInMs) }.onFailure { throwable -> Log.e("ShazamKitHelper", "Error during matchStream", throwable) } } } @JvmField var sharedAudioData: AudioData? = null; data class AudioData(val data: ByteArray, val meaningfulLengthInBytes: Int, val timestampInMs: Long) fun startListeningForMatches() { CoroutineScope(Dispatchers.IO).launch { streaming_session.recognitionResults().collect { matchResult -> when (matchResult) { is MatchResult.Match -> { val match = matchResult.matchedMediaItems println("Match found: ${match.get(0).title} by ${match.get(0).artist}") } is MatchResult.NoMatch -> { println("No match found") } is MatchResult.Error -> { val error = matchResult.exception println("Match error: ${error.message}") } } } } } } My code in java reads the samples from a thread: shazam_create_session(); while (audioRecord.getRecordingState() == AudioRecord.RECORDSTATE_RECORDING){ if (shazam_session_created){ byte[] buffer = new byte[288000];//max_shazam_seconds * sampleRate * 2]; audioRecord.read(buffer,0,buffer.length,AudioRecord.READ_BLOCKING); helper.sharedAudioData = new ShazamKitHelper.AudioData(buffer,buffer.length,System.currentTimeMillis()); helper.startMatching(); if (!listener_called){ listener_called = true; helper.startListeningForMatches(); } } else{ SystemClock.sleep(100); } } private void shazam_create_session() { MyDeveloperTokenProvider provider = new MyDeveloperTokenProvider(); AudioSampleRateInHz sample_rate = AudioSampleRateInHz.SAMPLE_RATE_48000; if (sampleRate == 44100) sample_rate = AudioSampleRateInHz.SAMPLE_RATE_44100; CompletableFuture<Unit> future = helper.createStreamingSessionAsync(provider, 288000, sample_rate); future.thenAccept(result -> { shazam_session_created = true; }); future.exceptionally(throwable -> { Toast.makeText(mine, "Failure", Toast.LENGTH_SHORT).show(); return null; }); } I Implemented the developer token in java as follows public static class MyDeveloperTokenProvider implements DeveloperTokenProvider { DeveloperToken the_token = null; @NonNull @Override public DeveloperToken provideDeveloperToken() { if (the_token == null){ try { the_token = generateDeveloperToken(); return the_token; } catch (NoSuchAlgorithmException | InvalidKeySpecException e) { throw new RuntimeException(e); } } else{ return the_token; } } @NonNull private DeveloperToken generateDeveloperToken() throws NoSuchAlgorithmException, InvalidKeySpecException { PKCS8EncodedKeySpec priPKCS8 = new PKCS8EncodedKeySpec(Decoders.BASE64.decode(p8)); PrivateKey appleKey = KeyFactory.getInstance("EC").generatePrivate(priPKCS8); Instant now = Instant.now(); Instant expiration = now.plus(Duration.ofDays(90)); String jwt = Jwts.builder() .header().add("alg", "ES256").add("kid", keyId).and() .issuer(teamId) .issuedAt(Date.from(now)) .expiration(Date.from(expiration)) .signWith(appleKey) // Specify algorithm explicitly .compact(); return new DeveloperToken(jwt); } }

HI Guys, I'm using Shazamkit in my IOS app and successfully capturing the currently playing track details, when using the devices (iPhone) built-in mic. When I test with AirPods though, my app cannot both send the output to through the AirPods and capture that same output with the AirPods mic, for Shazamkit recognition. I believe this must be possible, because the Shazamkit widget on IOS can do this. Is it restricted in some way for third party apps? If not, I'd appreciate some guidance on how to achieve this in Swift code. Thanks in advance.

Hello, Using ShazamKit, based on a shazam catalog result, would it be possible to detect the audio-recorded FPS (speed)? I'm thinking that the shazam catalog which was created from an audio file can be used to compare the speed of a live recorded audio. Thank you!

Hello fellow developers, I am developing a macOS app called "Playlist Plunderer 2," aimed at using AppleScript to control the Music app to play songs and employing ShazamKit to recognize these songs and update their metadata. Despite setting up the entitlements and plist files correctly, I'm encountering issues with gaining the necessary AppleScript permissions, and my app is not appearing under 'Automation' in System Preferences. Additionally, ShazamKit fails to match songs, consistently returning error 201. Here are the specifics of my setup and what I've tried so far: Xcode Version: 15.4, macOS 14.1.2 Entitlements Configured: Includes permissions for Apple events, audio input, and scripting targets for the Music app. Capabilities: ShazamKit and ScriptingBridge frameworks integrated, set to "Do Not Embed." Info.plist Adjustments: Added "Privacy - Microphone Usage Description." Scripting: Manual AppleScript commands outside of Xcode succeed, but the app's scripts do not trigger. Entitlements File: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.automation.apple-events</key> <true/> <key>com.apple.security.device.audio-input</key> <true/> <key>com.apple.security.files.user-selected.read-only</key> <true/> <key>com.apple.security.scripting-targets</key> <dict> <key>com.apple.Music</key> <array> <string>com.apple.Music.playback</string> <string>com.apple.Music.library.read-write</string> </array> </dict> </dict> </plist> I am having issues controlling the music app (itunes) from the apple script within my xcode project. the objective of the app is to rewrite the metadata of songs inside a folder in my Music app, this folder is titled Playlist Plunderer. The way I intend for the app to function is, the app will play the songs in the playlist, and then it will use shazamkit to recognize the song thats playing, it will then copy the metadata results of that song to rewrite the metadata of the song in the music playlist. I am still in the beginning stages. and I am very new to xcode. I created a apple developer account, paid the $99 and it is active, and I added the identifier bundle to the account from my app. I am VERY new to xcode,(this is my first project) my development team is set ( Shane Vincent), and the app is set to automatically manage signing, under app sandbox. i have audio input checked, under hardened runtime/ resource access audio input is checked. in build settings the path to the info.plist file is correct, the info.plist contains Privacy - Microphone Usage Description that I added i think it was called NSMmicriphone or something, with a description that reads "This app needs to access the microphone to identify songs using ShazamKit." the app appears under System Preferences > Security & Privacy > Privacy > Microphone but not under System Preferences > Security & Privacy > Privacy > Automation it is being made on macOS 14.1.2 (23B92) and xcode Version 15.4 (15F31d) Under framework library, and embedded content, I have added two frameworks, Shazamkit.framework, and ScriptingBridge.framework, both set to do not embed Current Issue: AppleScript fails to authorize with the Music app, and ShazamKit errors suggest an issue with song matching. Has anyone faced similar challenges or can offer guidance on how to ensure AppleScript and ShazamKit function correctly within a sandboxed macOS app? Any insights into troubleshooting or configuring entitlements more effectively would be greatly appreciated. Thanks for your help!

Shazam with IOS18 developer beta is not working. I’ve tried to reinstall the app but when the music sample is sent to the cloud i don’t recieve any answer

Hi Apple developers, Is it possible to display lyrics synchronized with a song in my app after the song has been identified? Just like the feature available in the general Shazam app when clicking on the middle-top icon (with music note in it) after Shazam'ing a song. The app I'm developing is intended for the Deaf and hard-of-hearing and therefore I would love to be able to show the song lyrics to make the app accessible. I would greatly appreciate your help because I can't find this in the documentation. Many thanks in advance!

Hello, I have a music on apple music. When I search this music on Shazam, I want it to appear with a clip like the link I provided below. Is there any way you can help with this?
