I wrote an article a few days ago“ Can iPhone also become a professional audio player? Introduction to popular portable DAC ”Later, many friends put forward that the iPhone does not support the import of conventional lossless music formats, even though it can decode the audio source with an external DAC. In addition, there are many false lossless music in the music of current online players, and it is not scientific to use iPhone as a turntable. For this reason, the editor decided to write a tutorial on the use of "ONKYO HF Player"

Many people who like to use iPhone as a turntable may already know ONKYO HF Player. As a music playing app, it can enable iPhone to decode DSDs [DSF or DFF] and 24bit/96kHz or 192kHz FLAC or WAV AIFF audio has the function of directly making a turntable to decode the USB sound card, which is extremely playable and functional. Because the settings of AIFF audio are slightly different according to the different sound sources when playing the above audio, let's take a look.

First of all, we need to know that if we want to enjoy the full blood version of HF Player, we need to first purchase its internal toll package, which is priced at 68 yuan. The price is small and expensive, but the resulting function expansion is absolutely worthy of its price. The internal purchase fee package provides FLAC, WAV, ALAC and AIFF formats for 24bit/192kHz (192kHz for external sound card, 96kHz for iPhone and iPad) Audio decoding; Support 64x DSD [2.8M] DFF and DSF file playback; It provides a 64 bit precision [optional 32-bit] equalizer [EQ, linear phase finite impulse response filter] with 16384 separate frequency bands; The external sound card can provide an integer multiple sampling rate up frequency function; DSD RAW data DoP mode playback [not converted to PCM] is supported in USB mode. The above functions bring the decoding ability and functionality of professional players to the iPhone. As a turntable, the bundled portable DAC expands its operability, expansibility and playability much better than most professional players at present.

For the first question, how can I import music in lossless format to iPhone? At this time, we need to synchronize iPhone and iTunes first, then enter the application list, slide the mouse to the bottom, and then we can see the HF Player in the application box. After clicking it, click Add Files on the right, and then you can pull all your favorite lossless music to iPhone. Although there are more steps, it is still easy to use. After adding files and synchronizing, We can see the corresponding files we just added in the HD track library of the playlist.

After the problem of importing files is solved, we will set HF Player according to different sound sources. After entering the setting page, we can first see the option of the up frequency mode, which can increase the SRC sampling rate by an integer multiple. When you connect an external portable DAC, you can set it according to different needs. If you plan to use the iPhone as the turntable output, it is recommended to open it. If you use the iPhone to directly output music, you can choose the 48kHz mode.

Then comes the play of this time, The DSD output format of HF Player can be divided into PCM and DoP. DoP can be understood as the turntable direct out mode. The sound source is directly output to the portable DAC without conversion for DSD decoding, which is very suitable for binding enthusiasts. PCM refers to that HF Player converts the sound source of DSD format into PCM code and then decodes and plays it. At this time, it can be played directly with iPhone, but with good quality.

Equalizer quality is available in HD and SD. HD mode is 64 bit precision operation, which is not a big problem nowadays. All iPhone models are equipped with 64 bit processors after 5s, but after the HD mode is turned on, the processor's computing load will increase and the power consumption will accelerate. Users can choose according to the power of the phone.

How about, after the introduction, do you have confidence in the iPhone as a turntable? There are actually many players like HF Player. In addition, iPhone is more convenient to operate, and peripheral portable DAC is more optional. In terms of playing methods, it is no less than the traditional professional players on the market. In addition, with the update of the app, the functionality of the player will improve all the way, It is absolutely suitable for audio enthusiasts. I will continue to collect more new ways of playing mobile phones for you in the future. Welcome to continue to pay attention.
