The Best Lossless Music Streaming Services in 2023
There are more lossless music streaming services than ever: Apple, Tidal, Amazon, Tidal, Deezer and Spotify (soon). Here's what you need to know.
What Is Lossless Music?
The term "lossless" was essentially created to be a foil — or to mean the opposite — of "compressed" or "lossy"; these are digital music files that have had a lot of their details, specifically their high and low frequencies, stripped away in order to save space on your smartphone or computer.
The term "lossless" doesn't mean uncompressed, however, but it refers to a type of compressed digital audio file that uses advanced data compression algorithms so that the audio track doesn't "lose" any detail in the compression process.
For context, the average size of a compressed audio file, like a MP3 or a AAC, is about 1/4 the size of its original recording. The average size of a lossless compressed audio file, such as FLAC or ALAC (Apple Lossless), is now a little more than 1/2 the size of its original recording.
When somebody refers to a "lossless" track, they typically mean that it's the same quality as a CD or vinyl record (16-bit/44.1 kHz). This was the highest resolution audio that many lossless streaming services (like Tidal, Deezer and Qobuz) offered for years, but many of them now offer ever higher resolution audio files, which are also a type of lossless music.
For example, Tidal gives its HiFi subscribers the option of listening to Master Quality Authenticated (MQA) certified tracks (up to 24bit/96kHz), while Amazon Music HD gives its subscribers the ability to listen to "Ultra HD" (up to 24-bit/192kHz).
Max resolution: Every lossless streaming service is capable of streaming CD quality (16-bit/44.1 kHz) audio, but that's really the bare minimum requirement. A lot of lossless streaming services now offer significantly higher-resolution tracks that are Master Quality Authenticated (MQA, up to 24bit/96kHz) or "Ultra HD" (up to 24-bit/192kHz).
Price: When Apple released a lossless tier of Apple Music at no extra cost, it definitely disrupted the existing lossless streaming market. In fact, every one of them was forced to lower its base price from between $15 —$20 to around $10 (which is the cost of Apple Music). However, most lossless streaming services charge more than $10 for lossless streaming, that's higher than CD quality. These more premium plans also can great you access to more features, like live concerts and discounts if you want to purchase certain lossless tracks.

Quantum Image Teleportation Protocol (QITP) and Quantum Audio Teleportation Protocol (QATP) by using Quantum Teleportation and Huffman Coding | IEEE Conference Publication | IEEE Xplore
In order to transmit images and audio securely, the authors present the Quantum Image Teleportation Protocol (QITP) and Quantum Audio Teleportation Protocol (QATP), which utilizes the Quantum Teleportation (QT) technique combined with Huffman Coding. The QITP secures the teleportation of quantum states of an image while simultaneously encrypting and decrypting them using Huffman Coding since it is only possible to recover or decode data if the prefix codes are known. To test their approach, the authors transformed pixels or RGB values from digital images into text, which was then fed into the Huffman Coding Technique. It has the advantage of compressing the entire text, which makes it faster to transmit vast amounts of information. This work also demonstrates the Quantum Audio Teleportation Protocol (QATP) with and without Huffman coding. For proof of concept, experimental evaluations were performed for both suggested QITPs and QATPs (Standard QITP, QITP with Huffman Coding, Standard QATP, QATP with Huffman Coding), using IBM Quantum Assembly Language (IBM QASM) Simulator and real quantum hardware using the Quantum Information Science Kit (Qiskit), a quantum computing platform.
Lossless and Near-Lossless Audio Compression Using Integer-Reversible Modulated Lapped Transforms - Microsoft Research
We present a simple lossless audio codec, composed of an integer-reversible modulated lapped transform (MLT) followed by a backward-adaptive run-length/Golomb-Rice (RLGR) encoder. Its compression performance matches those of state-of-the-art predictive codecs, and it has the advantage that its compressed bitstream contains frequency-domain data that can be used for applications such as search, identification, and visualization.

Improving Audio Compression
Audio compression is an essential process in music production and distribution, as it allows for smaller file sizes and faster streaming. However, current compression algorithms can lead to a loss of sound quality. Quantum computing could potentially be used to develop more efficient compression algorithms that preserve sound quality while reducing file sizes.
The parallel processing power of quantum computing could be particularly useful in this application. By simultaneously processing large amounts of data, quantum computers could potentially identify and eliminate redundancies in the audio data that are not perceptible to the human ear.
Music production and sound engineering are areas that have greatly benefited from advancements in technology, and I believe quantum computing has the potential to revolutionize these fields.
Quantum data are compressed for the first time – Physics World
Physicists manage to squeeze three qubits into two
A quantum analogue of data compression has been demonstrated for the first time in the lab. Physicists working in Canada and Japan have squeezed quantum information contained in three quantum bits (qubits) into two qubits.
Compression of classical data is a simple procedure that allows a string of information to take up less space in a computer’s memory. Given an unadulterated string of, for example, 1000 binary values, a computer could simply record the frequency of the 1s and 0s, which might require just a dozen or so binary values. Recording the information about the order of those 1s and 0s would require a slightly longer string, but it would probably still be shorter than the original sequence.
Quantum data are rather different, and it is not possible to simply determine the frequencies of 1s and 0s in a string of quantum information. The problem comes down to the peculiar nature of qubits, which, unlike classical bits, can be a 1, a 0 or some “superposition” of both values.
A user can indeed perform a measurement to record the “one-ness” of a qubit, but such a measurement would destroy any information about that qubit’s “zero-ness”. What is more, if a user then measures a second qubit prepared in an identical way, he or she might find a different value for its “one-ness” – because qubits do not specify unique values but only the probability of measurement outcomes.
“This way you can store the qubits until you know what question you’re interested in,” says Aephraim Steinberg of the University of Toronto. “Then you can measure x if you want to know x; and if you want to know z, you can measure z – whereas if you don’t store the qubits, you have to choose which measurements you want to do right now.”

Hi-res music streaming services compared: which should you subscribe to?
Tidal, Qobuz, Amazon Music and Apple Music all offer hi-res streaming tiers, but which deserves your monthly fee?
The battle to become the best music streaming service when it comes to offering hi-res streams is well and truly underway. Gone are the days when all a streaming platform had to do was offer up low-quality Ogg Vorbis or MP3 streams and make you endure a few ads for the privilege.
Today, the key to victory is ad-free, hardware-supported streaming in high-resolution audio quality – and, crucially, for the best price.
So where does the arrival of these newer, competitively priced hi-res services leave Tidal and Qobuz, and even services not in the hi-res game (Deezer 'only' offers CD quality, and the delay of Spotify HiFi leaves the world's most popular streaming service with some of the poorest-sounding streams)?
First things first, should you care about hi-res streaming? High-resolution (often shortened to 'hi-res') audio is a term used to describe music files that have a higher sampling frequency and/or bit depth than that of CD quality, which is specified at 16-bit/44.1kHz.
So a hi-res file can be 24-bit/44.1kHz, where bit-depth is higher than CD quality but the sampling rate is the same, and vice versa.
The highest quality MP3 has a bitrate of 320kbps. A 24-bit/192kHz file takes that to 9216kbps. Music CDs are 1411kbps – remember, they're your starting marker for hi-res.
Although hi-res audio songs and albums have been available to download for several years now, streaming hi-res audio is relatively new across popular music subscription platforms – and some still don't offer it.
While the terms 'lossless' and 'hi-res' may be used in close connection – Apple Music has launched Lossless and Hi-Res Lossless labels and, to complicate matters further, Amazon Music prefers the terms HD and UHD when referring to its more premium audio offerings – music that is 'lossless' is not always hi-res.
Why 24 bit/192kHz Music Downloads Make No Sense - VideoProc
In this guide, we will mainly talk about some information about 24 bit/192kHz music and show you why 24 bit/192kHz music downloads make no sense.
Decades ago, all mp3 encoders were really bad by today's standards. Plenty of these old, bad encoders are still in use, presumably because the licenses are cheaper and most people can't tell or don't care about the difference anyway. Why would any company spend money to fix what it's completely unaware is broken?
